As i stumbeled across this i found it is actually quite good, but as said in the 'does your school use Sandbox' board some guy said that it is good to start with but when your about 16 its time to move on to more 'professional' engines, does anyone know what engine may that be that is alot like this...

Hey im new to this so i am just wondering if sandbox has built in AI for NPC's, and can i cast spells on them and thay attack me like you know the basics.
