You mean graphic wise? I don't really mind that much in games, I care much more about design, immersion and athmosphere. I still like "AVP2's look" on the enviromnents and creatures more than in the newer games, AVP2010 copied AVP2004 style too much, AVP2 really captured well the feeling of the original movies IMO. Only Isolation reached that level.
Still I use a few mods in AVP2, nothing like AVP Classic's redux mod, just a few minor hd and texture updates, as well as some better creatures skins that made the game better than it already was. Even in other games like Gears of War, Unreal Tournament, Dead Space... the old outdated graphics from the first games just feel much better to look at, since the design makes up for it.
I would love a remake as well, but sometimes while the graphics look more realistic they can lose the athmosphere of the original game in the process and that kind of ruins for me a bit. Franchises like Halo did it well in the remakes, but Gears of War kind of changed a few things in it's look that bothered me.
AVP Extinction would also look great with new graphics, as well as Predator Concrete Jungle. Unfortunally all those Alien-Predator related game just didn't make much of an impact outside the fanbase.
