Heya, you're in the same boat as I am. Here's my list (excluding the ones you listed):
- Eternity Warriors 1,2,3 (3 would be great if they allowed you to actually play with people...so dumb)
- Hero Siege (single player, multiplayer coming soon) <---this one by far the best imo
- Darkstone (beta, just came out...not sure if this has multiplayer)
- Zenonia Online (english version unavailable yet)
