yukarihinata Crusader Kings 2. CIV 5. Unciv (opensource civ game that I've owned the android version for over 4 years). So mostly strategy, and stuff I can mod. I know some more obscure stuff like Niche - a genetics survival game, Crest and much more that lack active playerbases or any modding support.
My most played game has to be AWBW since I love strategy games with reactive thinking rather than long term memory. I would try out more stuff, but I lack diskspace on my laptop, can't afford a real battlestation and I have so much downloaded that I need to check it all out first.
Modding is also eating away on my free time, and the ck2 mp community being more active out of the blue too. I'm more keen on finding board game groups where I live, but those seem to be rather rare these days.
