The last two chapters in HL2 are the most memorable experiences in the game to me. From seeing the tower yards away from you (in Our Benefactors), which gave me a sense of awe tat I havent felt since I saw the T-Rex in Jurassic Park, to the ride in throught the building... to the end ;)
Personally I havent seen too much hacking, but then again i cant tell too much. I'd save the huge changes in gameplay (tanks, ect.) for CS2.
I would like more player models and possibly another V.I.P. mission.
