I caught a fair portion of Telltale Games' Batman at E3, and was impressed with what I saw. The crux of deciding when to be Bruce Wayne and when to be Batman is a really cool hook that could play out rather interestingly over the five episodes.
We have a release window for the series' debut as well now. The digital release has been given a window of August on PC, console and mobile, while a physical release will be available September 13th. That means that it really isn't long until we can expect to step into the cowl.
I really am interested to see how this now plays out, and importantly how often the episodes come. This could easily be the studios biggest release. Hopefully they can keep up with the demand of the casual market when it comes to frequency.
