As someone who just plays this game for the campaign and doesn't care about PVP (to be honest I didn't even know this existed in the Diablo franchise until now) this is a super solid game. It's basically a AAA Diablo game on your phone for free. The combat felt incredibly solid and satisfying and the touch controls felt better than any iPhone game I've played. I never felt compelled to buy microtransactions in the 10-15 hours I put into this, and got plenty of great loot. I had a ton of fun slaying demons on the go.
