Instant Endgame

I've been kicking an idea around for a while now - or better, a bunch of ideas have been kicking me around, I'm finally getting fed up with it. I started up a free forum some time ago, thinking to myself that it would be good to start running a bunch of play-by-post games there.
Have not yet started any, though I've populated and emptied, populated and emptied it a few times with different setting info and introductions and whatnot.

Never stuck - so I never opened it up for perusal or membership.

I've been running a 'sandbox' style PBP game at Vin's Trollbridge for a while now (roughly 6 months) and enjoying the hell out of it - first time I've been able to run T&T in too many years. Been dwarfing it up in noisms' Warhammer FRP for just as long. So I think that I've become somewhat accustomed to the peculiarities of online play.

So - what to do with the forum space I set aside for running games? I still don't know exactly, but my thoughts on the matter are turning ever more frequently to 3 ideas.

1. An Advanced Dungeons & Dragons (1e, mostly BtB, no UA) game with this premise: Characters are loaded on a boat at the behest of some Lord or King, who sends them to clear a wild island, to make it safe for further colonization.

2. A fantasy wargame. Rest assured, I do not intend to implement the 'game' presented in Galloway's Fantasy Wargaming book...(has anyone actually played this?) - no, I've been thinking instead that it would be interesting to have the players take on name-level roles, to determine their retainers and forces, fortifications and incomes and such, and play something more in the spirit of play-by-mail - where players have default orders, issue orders for their realm, and also decide on actions for their character as appropriate. Have no idea what game system to use for this - tempted to use Tunnels and Trolls, as it is the game I have the easiest time adapting to suit any purpose, but Rolemaster or AD&D could be serviceable also...with a dash of Diplomacy...

3. The Wizards War. Legends of many worlds tell of a time that wizards of great power came to conflict and brought wrack and ruin to each-other, wrought artifacts of awesome power, etc, etc, etc - 2 & 3 could really be the same game...

I dunno. I like the idea of refereeing a game where players are not necessarily co-operative, and maybe play-by-email is more conducive to this style, so that orders sent in remain private, and only published results offer information on the game-state.

Any interest, suggestions, thoughts, ideas, etc, are appreciated.
Cheers!
