Plays great, the touch controls work well. I love most of this type of games (baldur’s gate 1 and 2, divinity original sin, planescape, etc...) and this one does not disappoint. Got it for 5$, and not disappointed whatsoever.
I didn’t play the expansion content during my main story play through, and regretted it, since that would leave you higher level and with great items for the main quest. It still played well after, though.
