I have played CIV on the Switch. I just found the move from keyboard/mouse to control buttons and the significantly smaller screen size to be annoying. I choose to play Donkey Kong Tropical Freeze and Diablo 3 over it every single time. Just not a fun experience.
I hope it's sturdy enough to not be broken when I throw it against the wall after Rome 2 kicks my ass.
of more interest to me ... can you install TTS on it? and would it be usable? (not too small to have more than just a small percentage of the gameboard available at a time)
