mine are:
worms 2 (no other worms in the series but this one)
flashback
prince of persia 1&2
broken sword 2
need for speed 3
hardwar
just to name a few. many more but this is what pops to mind.
hardwar is a relaively unknown game (98') that still has a comunity today, with hacks and mods still coming out, 4 or so years after the producing company dissapeared (we will survive

).
The world would be in chaos if everyone would be like me.
