my personal all time favorite is the Grand Theft Auto series of games, and in that group i still like Vice City the best. the whole 80's theme was great and basicly reliving scar face too. San Andreas is a close 2nd. spending hours aimlessly doing basicly anything i wanted to kept me sane on days where insanity was preferred, the ability to drive anywhere, fly, boat, steal, kill, just the joy of distruction is ehough to keep me from going off and doing it for real...i've been playing GTA since its orginal top down version, which was also fun. Yeah, i know gta 3 has its flaws and what nots but its still a favorite of mine even with the popup problems.
