I would say automatically bundle a good waypointing system to work with, ala FBX.

From there you can have numerous things such as roaming controllers, or take a note from Q2 (I think) and have the player make a waypoint whenever he rounds the corner for the sake of better monster pursuit.

Appropriate target leading code for all manners of projectiles.

A concept of cover (this could be done by checking near by waypoints, and then crossreferencing it with the players position to see if there are obstacles between the player and the goal waypoint).

Intelligent checking for ledges that is sensitive to the player and the monsters ability (fiends should have no qualms leaping from a bridge).

Concepts of defense, so you can set a shambler that will not stray from the key.

Renegade's check for plat so monsters dont get stuck under func_plats or such.

Are we talking just monsters/bots or more generally?

I'd say scar3crow pretty much hit the nail on the head. I'd been pondering such things myself for TAKOP, but have been procrastinating on doing anything because I know it's gonna be a pain in the ass. (AI is definatly not my forte...)

Just wanted to point out that there are some useful bot AI functions in my Nexuiz port of dpmod havocbot, I've reorganized it a lot to be even more plugin than it was before, and separated the havocbot AI from the general utility functions.

Its concept of waypoints is not very efficient though, manually linking (ala frikbot) and saving the waypoint links would load faster.

Also there's a known bug with tracewalk sometimes returning success when it shouldn't (but only during the code that finds nearby waypoints to start a navigation update), I haven't figured out why.

Some other things worth considering (which my waypoint linking does not consider) are jumping over gaps (such as lava/slime pits), jumping off ledges (as opposed to just falling off them), buttons to open doors, etc, frikbot does these quite well but I'm not sure its navigation would be very portable to monsters.

My code does however automatically create teleporter and jump pad waypoints with proper one-way links, and the items spawn waypoints (which in a few levels are enough for bots to navigate a level without any extra waypoints).

Sorry, rambling, just thought I should point out this code incase it helps anyone developing such an AI lib.

Here's the main code:
