Complete(ish) wishlist:
So after being a member of generations for small while now,i think i'm ready for a wishlist,so lets begin

1.maps:A remake of Q1DM6 should be done,i know there is one but it's not too good because its not 99% true to the original.A final showdown map should be made for 2v2 deathmatch (just split the ctf version in half).
2.items:Not much here,though the strogg armors are not as cool as the originals
3.models.Remaking the old quake 2 models (not really as grunt skins) would real awesome.
4.game modes: a ffa clan arena would be awesomeeee,some kind of monster hunt mode could be epic,and team  elimanation(without the full arsenal and ammo+health)and some u.t assault mode,it be cool
  4.5:campaign mode-ok here we go, bundle 32 maps (2 secret) into 4 episodes (1.E.S,2.Doom,3.Slipgate,4.Strogg)you could have people vote for their favorite maps per episode.it could also be played with 1-7 other people for co-op;also at the the beginning you can choose your favorite generation of all to play as. Oh and at the of some episodes you could returned to a Q1 style hub entrances

How about a modified ut assault that won't be exact or over the top limits but feel some reminiscence of it, there'll be 2 teams one defending the base and the other assaulting. Instead of destroying an object it could be a flag that would be captured somewhere in the base or back to the spawn point.

 Here's another simpler gametype tactical dm or ctf.
It could take place in big maps with lots of players. two teams would normally spawn with a twist, your team has limited lives,(if a player dies they will lose a life and has to use another)and will have to eliminate the other teams lives until they lose,ammo will be limited and health is scarce.
For this it would be freakin' awesome if you could jump out of airplanes for an attacking/reinforcements team and also classes within classes(a strogg trooper assault guy,he would have some grenades and a mg,or an earth soldier demolition guy would have mortar and grenades)i dont know i keep coming up with cool ideas so... yeah   
 
 One last gamemode is melee mayhem, players are stripped from their machineguns and boomsticks and forced to use melee weapons. To add realism adrenaline pumps in so they'll move faster and stab faster, adding to the fun random powersups are given to random players that could help or hurt them; could be turned into tag mode.(for stroggs give em the ground zero chainsaw if possible.)

Awesome, thanks Pho!

While making an entirely new Cyberdemon model would be a lot of work, and impractical gameplay-wise due to its large size not aligning with the standard hitboxes, it occurs to me that a Hell Baron or min-Cyberdemon skin for Klesk in the vein of Tab's Death Knight skin would be a sensible compromise.

Uuum, wouldn't holding the guns in his hand like 99% of the other playable characters make him fit in more?

Also, how would you make an Imp skin for Klesk when Imps don't have horns on their heads? Also, there's already an Imp model for Q3.

Just sayin'.

I merely meant that it would look more natural to have an armed Cyberdemon. Also, I think that the Cyberdemon is far more interesting to look at. To me, the Baron (and Hell Knight) always looked like a pretty generic demon. Of course, given their similar shape, it doesn't seem too far fetched that one would lead to the easier creation of the other. The Cyberdemon has a few extra pieces, so I don't think you could merely skin it to and from the Baron. Though perhaps you could used the "cleaner" outlines of the Baron/HellKnight as a base for a more intricate Cyberdemon model? Just thinking, of course.

Yes, there is already a very fine looking Imp model available for Q3. There is also a similarly finished Arachnotron and Revenant for that matter. There are also a couple of very high quality Strogg player models out there as well. If I recall, there is the Gladiator and the Iron Maiden. Of course, the problem with using any these is that Wirehead would first have to get permission from the original authors to modify them. Then depending upon how they were originally built, modifying them for the new animations system may not be the easiest task in the world.

I don't necessarily want Klesk to become an Imp, but I assumed that was the original intent given his assigned generation. Still, I think a serviceable skin could be possible. If you're really worried about the spikes, just keep in mind that they could be given a transparency with a new skin. You wouldn't even know they existed.

On the issue of skins... it wouldn't be too hard to make a "Grunt" enemy skin for Ranger.

Again though, this is just flight-of-fantasy, "wishlist" material. It never hurts to toss ideas around, but I wouldn't count on any of them being used. Especially not when getting all of the vanilla Q3 models working is of a higher priority. I do miss being able to use Tabun's Enforcer and Guard models, too. Hehe.

I kinda doubt many have played the PS2 vesrion of Quake 3 but I wouldn't mind seeing bits of that implemented into single player Generations.

Namely the final "boss" fight where If I remember right you had to fight a few other opponents in different small arenas before teleporting to the final arena that had one of the vadrigar you had to kill...

Again that's if I'm remembering correctly...

 Maybe all the monsters should be a separate class. It would be a DM mode were it's the monsters of the id games vs. the 5 standard generations. The objective for the monster team is to achieve as many points(obviously) and along the way the monsters could be upgraded if enough points are achieved.

• 0 Points: Light Guard: Fairly weak but fast and carries high quantities of ammo, capable of carrying multiple weapons.
      Upgrade: 4 Points, turns into QEnforcer: Sturdy goon with decent fire power.
• 8 Points: Imp: Well rounded average monster, can be deadly if gathered in groups.
      Upgrade: 12 Points, turns into Superior Imp: An enraged Imp capable of spawning Lost Souls.
• 16 Points: Iron Maiden: Powerful with rockets but very vulnerable.
      Upgrade: 20 Points, turns into Ogre, slow moving tank.
• 24 Points: Mutant: A fast and devastating foe with weaknesses.
      Upgrade: 28 Points Fiend: Fastest monster out there, can give a real thrill.
• 32 Points: HellKnight, an all-around foe, very powerful.
      Upgrade: 36 Points Baron of Hell: A near unstoppable spawn of hell.
• 40 Points: Shambler, rocket consuming electric abomination.
      Upgrade: 50 Points: Cyberdemon: Nightmare.

 That would be awesome, but being realistic, it'll take ages to model and animate, most will end up being skins. Could be used as an Invasion type mode from UT2004. 

Colors can be assigned to classes via their own config, that hold weapon key bindings.
I did classic selection of crosshairs that way too. 

color1
color2
cg_drawcrosshair

Using "color2 0" can even make doom plasma "classic default" color, with saving difference for anyone else selections.

I take default crosshair from original and set closest available crosshair from available in q3, or take some imagination if there was no in original game.

Slipgate/quake 1 it was actually add sing/letter +, cg_drawcrosshair 1
Strogg/quake 2 it was similar but without center piece, cg_drawcrosshair 2
Quake 3 empty circle with dot inside, cg_drawcrosshair 4
Doom had none but you need some indicator for long chaingun sniping so i took dot, cg_drawcrosshair 5
Earth also had none, but his main weapons are gatlings he needs rough indicator of bullet spread so i use filled circle with dot, and surprisingly it matches with it more or less, cg_drawcrosshair 3

And some original sound taken from my collection of above games, with some twists like q2 railgun being makrons railgun, and single gatling taken from team arenas gatling.

Far from it.

TBH I'd love to see the PS2-only maps redone for Q3. That final map in particular ("Final Resting Place") would make a great duel map with some item optimization.
