Wargame vs "Living world"

[Hoofhurr]

Along these lines I never understood why developers never built more GM tools into their games. EQ probably came the closest but there's stuff you could do where you wouldn't have to have a host of employees controlling single NPCs. Why couldn't you let GMs control spawn rates or start small scripts where eventually two sides of NPCs have overlapping paths and battle it out? These events could occur simultaneously over all shards(assuming shards) and it would just be some dude playing the game from the side of the computer like some wizard of oz type shit.

Improvisation in live music doesn't always work out but you get those golden moments that make continuously trying it out worth it.

Do glitches in games really bother you guys? (Not being able to cast on people in water) Or do you think that players adapt to those things and they end up giving the game its character and flavor?
