1. Puzzle Pirates
Full market economy, puzzles for conflict, jobs, and crafting.
2. EVE Online
Single server, hands-off approach to disputes, great way to distract griefers so we can get around to secretly building our online utopias.
3. A Tale in the Desert
Finite project to be completed (new projects mean new games), full spectrum of roles to play, not just the usual RPG tropes.
3D RTS with an impressionistic graphical style and crazy-ass AI behavior.
