I hate rebuying stuff I already have, but I’ll pick up Diablo 3 for sure. Especially since it is a complete package with everything.
I’ll see whether or not I pick up Civ VI when it comes, but it annoys me that they release it without the expansion integrated. I haven’t bought the expansion on PC yet, so that would have been an added draw since I might actually end up playing it on the go whereas I never seem to get around to playing it when at home.
