I haven't played it. My impression is that it was trying very hard to cater to the mobile market. I heard it suffered from a lot of design changes and ended up being sold and then patched up and released by a new team to cut their losses. Meanwhile, Torchlight 2 may be older but it was made with love and care and a strong vision. It's dirt cheap now too so it's not hard to get your money's worth out of it.
