I'm not sure about the Magic one, interesting idea and scenario but I think the powers won?t work well. People will complain about them being left with lame old illusion and then this will lead to people using illusion on other people and make them run off a cliff out of pure spite. However if you make control over the use of the magic then that kind of ruins the whole point of RP with magic.
Also I'm sure time zones differences will ruin any battle with the monster. Some people would need to stay up into the wee hours of the morning just to be able to fight your monsters at the same time as your controlling them. Maybe if you just let the monsters be controlled by other players who are fighting them (similar to the Troll Slayings) then it might work. Still during these battles you'll have the dickhead who has illusion make the monster invisible or something, and then make the players run off a cliff.
If this does go ahead however, can I be the guy with Illusion.
