Ever, Jane is a new type of MMO: there are no dungeons, swords, guns or spells. Instead, it is set in the polite society of Regency England. Your goals are to advance your status by attending balls, making matches, and vicious gossiping.
Even though I’m not a fan of Austen’s work (I appreciate it — it’s just not for me), I’ve often wondered how one would build a computer game with a non-combat conflict resolution mechanic. Tabletop RPGs have a whole indie niche dedicated to this (and there’s always freeforms), but this would be my first encounter with a computer game that attempted this.
