I've been getting back into the classic Close Combat games, and they're some of my very favorite of the wargame genre.
I'm curious what retrogaming's favorites are. I'm not too particular on what constitutes a "wargame," it could be anything from Final Fantasy Tactics to Steel Panthers.
To throw a couple more out, I really enjoyed Rome: Total War for the 4x strategy and the Combat Mission games for their simulation systems as well.
There was an old fighter pilot game that I used to play on linux back in the day all the time in the early 2000s. I can't remember the name but it was because my dad's laptop was very cool to me and ran SUSE, so I played that, super tux, and a few free games because the alternative was a windows 95 machine with a 10 gig upgraded hard drive.
