It's a traditional RPG in the same way that Dreamfall is a traditional adventure. No wait, I mean in the way that Fahrenheit is a traditional adventure. Damn! Alright, alright, it's like Full Throttle! Except it's an RPG.
Sorry.
In all seriousness, it has characters that level up and have different skills that can be improved, but it also has real-time combat. Action-RPG if you will.
