Master of Orion 3

One of the ULTIMATE, ADHD, coping tools. I can fixate on this game for HOURS! and older machines are what it was designed for.

Look, you've heard it sucks. And sure, there are a lot of issues, but for some reason, perhaps because I like the way the carrier battles look, I have every five years or so returned to this game since it came out when I was eighteen. Maybe nostolgia has something to do with it, except I actually bounced the first time I played it (because of the things that you have heard about that make the game suck), and only enjoyed playing it when I tried it again a few years later. Look up the standard mods, and try it. It's weird, but in an interesting way.
