In particular if you're doing pathing for tons of npcs (as they are) you really want to keep that optimized. In Guild Wars at launch for one of our expansions we had huge CPU issues with our game servers - it turned out designers had laid down really long elaborate paths for NPCs like guards and townspeople and the server was calculating all those paths at once when players entered a new zone, so it was saturating the game server. I had to build an auditing tool so we could scan all the zones for long paths and replace them with simple ones.

Bethesda has been building this specific type of game for decades so at this point things like npcs having complex patrols or other behavior is something they've figured out how to do well.

I played a lot of Guild Wars when I was a teenager with my friends! We were very glad to have a MMO that was fun and had raids, even though we couldn’t afford the other ones with a monthly cost. It was also prettier than other games. I still remember many of the locations :)
