I do agree that they make too many Batman figures. The worst part is that they aren't even different versions of Batman. Making Batman from the Dark Knight, Arkham Asylum, Arkham City, and their own version is fine since those are 4 completely different version of Batman (just like KH1 Sora, KH2 Sora, DDD Sora, etc.). Where I think they cross the line is when they release, LE San Diego Comic con Black/White Arkham City Batman which is the exact same figure of Batman from Arkham City, just pre-production and not painted. Here are my gripes with that:
1) It's the exact same figure model
2) They just got lazy and didn't even paint it
3) They are increasing the pricetag slightly on something that has less effort in it.
I do think they are making a lot though and I would like they focus on KH. They clearly aren't dropping their own games though since they have had a constant stream of FF figures every now and then. Not as many as they used to (they made the entire main cast of FFXIII, but they never made a Noel figure for XIII-2. I know, the second protagonist of a huge game and they never made him), but a nice amount still.
My problem with all the Soras isn't the fact that they're Sora, but is pretty much like my problem with the Batman things. The Sora they used for most of the figures is the exact same model. KH2, Valor, Wisdom, Master, Final, and Limit use the exact same model and while it makes sense that they should, I think instead of making 5 other figures with new clothes, they should have made 1-2 brand new figures with different models (KH2 Riku was an obvious choice at the time).
If they were planning on doing a different Sora, I kind of wished it was one that was very different that required a new model, like Christmastown. I've always secretly (not so secret anymore) wanted them to make an Atlantica one but that'll never happen purely because I don't know how they get the tail to work really well.
