I wrote some BBS door games back in the day and was thinking of making a new one today, although not multi-player. It would be in the style of the old games (ANSI-style art and text) but for a single-player and with a daily play limitation as well. You'd only play a few minutes each day and if you died, you'd have to come back the next day. Nothing concrete yet, but I definitely would like to make one just for old time's sake.
