True. On a modern PC you could just brute force everything and it would still run fine as long it was cache friendly I suppose. 1000 NPCs is still only like 499,500 + n * direction checks or whatever. Nowadays the mentality seems to be about running more threads. I just like how some of the older *classic* games went about solving problems differently than we do today. I think it's easy to take this stuff for granted when you have a gaming PC or PS4 hardware. I don't know, I just find it neat I guess. :)
