Most favorite: CB, LSL & SQ3
CB had a great atmosphere, and like LSL & SQ3, it was a good, playable adventure...
And I'd have to say: I really hated ICEMAN after a while... It was one copy-protection infested, follow the correct procedure crap, difficult arcade sequences, not 'open' at all, piece of game... And PQ2 wasn't really fun, playing the same over and over again cause you could 'forget' something, without knowing you did (like somekind of kit in the beginning) and play half the game to find out. I'm not saying I don't like them at all (yeah, I know I said "hated"), but I like them the least...
PS: I remind that they (ICEMAN & PQ2) had the same designers, however, I do like their other games......
