SEGA X Nintendo: Demolition

Sega X Nintendo (Typecast as "SEGA Cross Nintendo") is an RPG-based fighter published by Sega and developed by Nintendo and Dimps. Its gameplay is loosely similar to the Japan-only Namco X Capcom, but has more of a Guilty Gear-like esque. Unlike Namco X Capcom, however, not every character from both the Sega and Nintendo universes is present... Each universe actually makes up of 25 characters. This is also for the Nintendo Wii and Nintendo 3DS systems.
