Warzone 2100 VS Tales of Maj'Eyal (ToME)

It is more an RTS than a 'classical' wargame, but you could do it in Warzone 2100. It is old for now (but it was very fun in 2000s). It could be fun for you today. There is a free and open source version : https://wz2100.net/ . Source: 5 months ago

I never had any problems running it on mine, but Warzone is a very old game. Are you using the latest version? https://wz2100.net/. Source: 11 months ago

Since Brogue's already been mentioned, I'd add Dungeon Crawl Stone Soup and Tales of Maj Eyal as pretty beginner friendly games. Source: 5 months ago

Have you tried TOME? It's a free roguelike, but you can also buy it and the DLC (sold for $4-7 on his website) on Steam if you end up enjoying it. Source: 10 months ago

Try the free download from te4.org first! That is the full game, not a demo. It doesn't have the DLC, but then for most of its existence there were no DLC. I've spent years playing the main campaign before the DLC. Just the main game is huge and has lots of content. Source: 10 months ago

Also, what's the difference between the steam collector's edition and the te4.org version? I absolutely don't mind paying 10 eur, but first I want to clarify what's the difference. Source: 10 months ago

If you don't care about graphics. This could be right down your alley Https://te4.org/. Source: 10 months ago
