|80286 PC/DOS :||Blockout,
which can be played with your feet up
bcause it doesn't use the mouse.
|386 PC/DOS :||Sid Meier's
|Pentium PC/Win95 :||Civ
a refined version of Civilization.
A previous sequel to Civ, Colonization, is OK to play for a while, but in that game the level of detail in what you control is a bit too high even for my taste.
A multi-user variant of Civ, FreeCiv, is now available for downloading if you are using UNIX and X11. It is great fun!
Other games I like are Stronghold, Tetris, Empire, The Alone in the Dark series, all Sierra adventure ("*quest") games, Dungeon Hack, Hand of Fate, Arena, Jagged Alliance, Worms, Civilization (the computer version of the board game, quite different from Microprose's), and all kinds of adventure/dungeon games, strategy games, and multi-player games with neat sound effects.
I used to play a lot of mud, but I haven't played it at all for many years now.
I also play some play-by-mail games, both snail mail and e-mail.
