Hi Lance, just seen you responded a couple of months later! On the off-hand chance you're still around, I figured I should invite you to the
Fixed Camera Appreciation Society, a Steam Group I set up some time after trying to find places to talk about fixed multicam games. =)
On your points, I dunno if we can only differentiate games based on gameplay. I think camera choice and implementation is as key as whether you're using a mouse or gamepad or who your character is. Camera choice defines what primary information most players are given about their environment - and being able to restrict that information can be an interesting tool for a developer.
Lots of Fixed Multicam games coming out this year! Come along, join us and explore the history and future of this awesome approach! =D
(And, yeah, it turns out Life is Strange isn't fixed multicam. Great games, though...!)
