Anyone know a basic mob movement system and if they see the player they will choose from either Attack, or skill1, skill2, etc.

thanks
Do you mean AI (NPC's that do stuff based on their environment/vars)? If so, there are many libraries/demos on the matter, so you should try searching AI.

EDIT: Searching AI gives no results, but after a few seconds I found a good demo, hub://XstreamSage/MonsterAI.
