That I (still) own?
-
GoldenEye 007 (N64, 1997) (on 'Agent' [easy] and 'Secret Agent' [medium] difficulties; never did manage to get very far on '00 Agent' [hard])
- If you count somewhat more open-ended, replayable games,
Discovery: In the Steps of Columbus (DOS - PC, 1992)
- If you count freeware,
Castle of the Winds (Windows 3.x - PC, released 1992 or 1993, depending where you look, but
NOT 1989, as some sites claim) (pity so many of the pages hosting it / talking about it have gone down in the last several years -- not to mention the convoluted process required to get it running on 64-bit Windows)
- And finally, if you want to count "casual" video games, the version of MS
Solitaire and
Minesweeper that came with Windows 3.11 would probably count as being from that same era (
Solitaire is the older), and I certainly "beat" them both many times. =)
I don't really finish very many of the games that I play, though -- not as a kid, and not now.
