PC - Jagged Alliance 2
Console - Super Mario 64

Prince of Persia in an old computer my parents had. And I thought the graphics were amazing!

If you mean first game ever, it'd be probably Bio Menace or Commander Keen.
If you mean first game on Steam, it was Killing Floor.

Tetris

Oh well for me it would be Super Mario.

Hardest game evvah :3

Micro Machines on one of Famicom/NES clones

As much as I loved games on our Nintendo devices (We had a few consoles and such), I never really had enough patience to play a full hour on there. The first game I ever played an hour of, which it's actually the game that got me into gaming, is World Of Warcraft. Although I quit. Within an hour, I got to level 5 and I wanted to explore. Well I went too far and I couldn't get back because everything kept killing me and I'd respawn in the same place over and over and I couldn't get anywhere so I quit. This was 3 years ago lol.

GTA 1 Demo with the approx. timelimit of 10 minutes :)
