As did I back in the day. But now I'm older with less time to micromanage pathfinding. And our devices are much faster than when many of these games launched
Well, in general, the rest of the answer to your question is that newer games tend to have better pathfinding, but adding better pathfinding to older games will make them essentially different games. Casual players might like it; serious players would throw a shit-fit. It's one of those "we can, but should we?" questions; everyone's going to have a different opinion.
Now...I don't see why they couldn't have included it as a toggle-able option. I know that I've considered trying to build updated versions of old games, and when thinking about how to do it, that seemed like the best choice.
