I've played all of them and I really enjoyed 1 and 2! I have played and beaten 3 but I can't possibly tell you anything about the plot because I literally don't remember it. I just remember farming levels on the last map at the end of the game because it was amazing experience. Definitely give 1 and 2 a chance and just forget about 3.

I can see them doing like, "Switch Up"

Currently reading/listening to the Dresden series, on White Night right now, listening while I travel for work and the books are great fun
