Good read. The article mentions people being happy with Miles and it being a possible way to stop-gap, and I don't necessarily disagree outright but I do worry that flooding the market with interim games in the same engine might get a little tiring. I mean, that was part of people's issues with Assassin's Creed and far cry.
Granted, it's Spider-Man with a number of variants, so there is a bit more differentiation. Playing 1, Miles, 2, and whatever the next is are all fairly different so it feels more like the Arkham games than the Ubisoft ones. I just worry that if we get a in-betweener for every major release it might get a little stale.
