The question is, now what? What to do to get replay value out of the game? Some thoughts that have occurred to me:
-Try and program some AI scripts. If I could use this feature to program a pathfinding AI that didn't get stuck in empty rooms and behind open doors, I'd be all over this.

-Try different character-building approaches. I've never seen much use to the various "archetypes" - the more specialized ones, such as thief, seem fairly useless, and most of the rest are only a few skill points away from being identical. But maybe I could develop the character along different lines - focus more on spell-casting, build a bare-hand fighter, or the like.
-Create arbitrary challenges. How many quests can I have remaining unfinished when I beat the game? How many quests can I avoid receiving altogether? Can I manage to have Timon, Aethon, Hector, Meleager, Ariadne, and Dryas all in my party simultaneously? Can I beat the game without ever being joined by Hector, Meleager, or Aethon? Can I kill a polyp or Scylla while armed only with a rolling pin, ceremonial axe, or equally useless item? Can I single-handedly depopulate Cademia?
...Anyway, I've rambled enough. My question to you is this - what do you do in playing Cythera to maintain your interest in the game?

Sometimes I think we're not.
In either case, the thought is quite staggering.
