Hi,

I’ve been doing some reading lately on game AI and wondering where to place the logic n decision making in an online game environment. For an offline game, the AI can be processed on the game client. However, after much thoughts I can’t decide where to process it in an online game like mmorpg.

Since all users need to be in sync, I thought they should be done on the server. But it seems like it may be too heavy for server n also bandwidth. Then, I thought it can be done on the client and decided by a master player. But then who shnuld be the master player and can I trust the player’s data?

Right now, I am really thinking how to sync NPCs and monsters AI without putting too much load on the server. This will be my first for AI in online games. Any thoughts?
