Multiplayer RPG & Multiplayer Kids Game?

I'm looking for both a multi-player RPG and a multiplayer kids game.

RPG:
I'm NOT looking for a MMORPG. I'm looking for something more like LAN or server play. Some sort of BG2 thing would be preferred, but an action RPG like Diablo would be ok, as long as it wasn't too much FPS'isy ... one party has a poor twitch response. I know about the BG line, the NWN line, and the Diablo/Dungeon Siege line. PC, Wii, 360, PS3 ... the game system doesn't matter, the multiplayer RPG does. (I'm also familiair with the D&D line for the 360, xbox, those have been played out also.)


Kid

PC only? Something like multiplayer hamsterball or monkeyball?


Any ideas anyone?
