I always enjoyed the classic BattleTech game from FASA. However, the game tended to take a long time to play if you got into any decent-sized battle, as well as taking up a lot of room (and requiring many miniatures, etc. etc.). The game's a ton of fun, but the WAF (wife acceptance factor) of all that STUFF and time commitment is not very high. A long time ago I ran a PBM BattleTech tournament, but I had to do everything by hand. Not something I've since cared to repeat.
Anyway, what I want is an online version of the classic boardgame. I do not want a first person Mechwarrior clone. I want to be able to create a hex map, create the various mechs involved, assign them to teams, and then play the game with my buddies in a turn-based fashion whenever it's convenient for us. Does such a game exist (either officially or a clone)?
