Nostalgic for Empire and other early daily turn based games

Recently I've been really nostalgic for really simple, daily turn-based games. Not sure how many people here may have played Empire, but this is what I'm talking about. I very fondly remember dialing in (with a modem) to 4-5 different Unix based BBSes just to play Empire every day. Each day your turn may take 10 minutes. This is the key thing I am nostalgic about...really low time investment every single day, but in a game with lot's of other players.

Other games that I really enjoyed back then were the BBS "door games" like Tradewars. Tradewars can still be played via telnetting into various BBSes that people are keeping up and running.

So, now that I've set the scene, what are the really simple games out there that you may play that are daily turn-based?

Second question, what would people think about a web based version of Empire? I'm thinking of building it, if I don't find the existence of it somewhere already. I think it would be really cool to have someone drop by the web site, click play, and have them thrown into a map with other players (up to 30 per a map or so).
