XCOM? RPG? I know people like to have an offensively wide interpretations of "RPG", but.. really?
Yeah I guess it is more of a tactical war game, but it has a story so it is an adventure game. Not really any role playing in it, but honestly I don't put much in the importance of "role playing" anymore. Mostly just enjoying the story, and the branching results of decisions. It still resembles a good number of RPG mechanics though, same principle. Basic attack, special attack (spells), turn based.
I know some would try to compare it as a shooter, but I could never call it that. To me a shooter is like Mass Effect, or Gears.
