I'm looking for a game with all of the following features:
- no fantasy, no sci-fi
- modern warfare (that is, post WW2)
and at least 1 of the following:
- runs on Linux (without wine)
- is somewhat popular: has streamers or lots of existing videos (regardless of age)
I spend daily a small amount of time playing games or watching streams, so why not combine it with learning (arguably) useful concepts.
For example, games like Age of Empires, Civilization, Empire Earth, taught me how insignificant the life of a soldier or villager is to a "successful" leader, and that destroying other nations to steal their resources is a very effective strategy (and used up to this day). Also taught me the effectiveness of focus-fire (that is, concentration of force).
Note: I used to play People's Generals, an old turn based strategy game (>10 year old), hex map, with Patriot missiles, entrenched units, etc but it was Windows only. A game similar to this, with the above restrictions, would be great.
