We are old nostalgic :D
I'm 27 but I've started to play very early with the Sinclair ZX Spectrum and the old school gameplay now remind me the good old days!
Those games are milestones that almost every computer may execute, they are patched and came along with expansions without need to wait. And of course, they are quite cheap!
Someone has named Voodoo cards: I've collected about 110 +/- 3Dfx cards and hundreds of other brands (Voodoo5 6000, 3D Prophet 4800, Diamond Edge 3D, ...). It's a pleasure to build up a perfect configuration, specific for one game!
