Nipples: The bigger the better.
Not if they slowly become tit burgers/chocolate digestives, or as a worst case scenario: Furry Tit Burgers. Had an experiance with the latter (FTB) and let me tell you, i was ever so slightly freaked out. I say ever so slightly, what i did was looked, froze, turned around, walked out the door, and just walked back to my room in a daze. Not nice.
Oh and i do remember Lithium Quake2. That was very good indeed. Although i do think the best mod for Q2 was Action Q2. Much better than the HL version of it.
Personally i think Q4 will play just like Q2 except with D3 graphics. Not necessarily a bad thing at all.
Just wondering though, are there any psycological horror FPS games out? Like a game thats basically the "Haunted Hotel" mission in Vampire: Bloodlines all the way through? I much prefer that sort of media where you dont have to see something scary to get scared, but instead theres a constant tension building with wierd noises, strange sights and just generally freaky things happening (that man with the axe walking slowly towards me freaked me out so much in the boiler room of the hotel).
