Heimdall 1 and 2 are very fun, even if the combat in both can be a bit tedious.
Hilt is a fun rogue like. It almost plays like a MUD but with 4 characters. Would probably do great for hotseat play too.
I really enjoyed Dragonstone for a "zelda like" type of game. Played Darkmere a bit and it seemed awesome, but I didn't play it extensively.
