Oh yeah, I’m playing Unicorn Overlord right now! It scratches that same itch, and I’ve really been enjoying it. It’s a little easier than I’d like, so you can pretty comfortably crank up the difficulty to the highest setting for a decent challenge.
If you like this genre (whatever it would be called), you might also like Symphony of War on PC. I played it a couple of years ago, and it’s really good. It was the first game I’d played like Ogre Battle 64 since I was a kid.
I still frequently play the newer xcom 1-2. I really want to play the originals, but I feel like I need to read some guide of the basics, since it’s not very clear. I assume back in the day there must have been a manual or something to reference.
