Broken Sword 2 , than the second monkey island, myst,and so on .
Weird enough on a 120 MHZ pentium ,on Windows 95, 16mb ram which was actually my first PC, and was all I could get!
I started to love the adventure genre and I now play old games and new but despite that I'm still the person that would mostly prefer a nice 2d point and click from the 90's over a high-tech 3d game!
