I am just a pc gamer, no consoles
.
in no particular order (except maybe for n°1)
1:Monkey Island I & II
2:PES *insert most recent version's number*
3:Half Life 2
4: Dune 2
5:Gta San Andreas
6:Bioforge
7:U.F.O. enemy unknown
8:Alone in The Dark
9:Micromachines 2
10:Sensible Soccer
There are a bunch of others really good games I played through the years, these are probably the most "important" ones.
Quite a nostalgic list, actually.
