A tough month for a change! There are at least five games in the main poll that interest me, and another one outside of it (Total War: Pharaoh).
I think I'm most interested in seeing whether Lords of the Fallen improves on the first game enough to make it a great Soulslike (it became a bit of a walkover after a while because of poor balance). If it does, I can see myself enjoying it as much as I do the Souls series. But that's a pretty big 'if'.
Forza, Super Mario Bros. Wonder, and Cities: Skylines II should all be reliably great. I'm also interested in Spider-Man 2, but still have to get round to the original game first.
