What I am searching for is for games that support touch screens and can be played with 1 finger / one hand. No action games with fake joysticks on the screen, just games that work with a single finger or at least one hand while lying in bed and trying to wind down. One very good example is Civilization V, which has a dedicated touch screen mode and is a turn based game. Also the windows included card games work good.
I tried to search for games on Steam, but unfortunately there is rarely a tag for touch screen support. Even Civ V with its dedicated touch screen mode has no tags telling about it in the Steam store, so it is hard to find games that work well.
I thought the "The Room" series could work well, because they are awesome on IOS devices, but the Windows version on a touch screen is cumbersome to use. So you can not even look out for mobile games that also exist for Windows.
If someone has some recommendations, I would appreciate that very much :-)
Edit: Changed Civ IV to V!
Tinyfolks is a little indie turn-based roguelike you can compete a run of in a few hours. It's like Darkest Dungeon except with the opposite amount of stress, and it actually only supports mouse/touchscreen!
Oh cool. That looks like it might also be a battery saver and not causing too much excess heat in the tablet :-)
Definitely not a resource-intensive game!
