hrmm.. cod2 is far off from bioshock... now 4 is a different story... only thing i don't like about part 4 is that lots of surrounding details looks like crap.. and again, the game is very linear and scripted.. and not only that, gun sound quality is utter crap.... i should be able to turn my speakers up way loud and expect to feel bass from a rocket launcher.. and all sorts of warfare w/ guns.. but again, as part 2, failed me miserably....
now a game that captured all elements of sound, visual, and a certain sense of realism, would have to be crysis... the gun sounds were amazing, enemy tactics were pretty smart... and they actually reacted like normal people at times.. and would freak the **** out... i mean.. who wouldnt after you saw a freakin invisible man!!!!
anywho, bioshock needs to finish torrenting, i loved the demo
