The title asks it all, is this a big stand alone one or just a small expansion?
Personally I dislike Teen titans Go and would prefer Young Justice, the original Teen Titans Cartoon, or even the Original Shared Animated Universe.
This will be a standalone game for two players using the Cerberus Engine. Because of this it can be used to expand any of those games. It will work very well with Cartoon Network Crossover Crisis Deck-Building Game
