Hmm... DOA4 I would say is the massive receipient of being in the right place at the right time. The Fighting Game genre was in a bit of a slump back then and a casual scrub friendly FG like DOA4 with impressive online offering would make a splash. Both DOA5 and to a lesser extent DOA6 released at bad times in comparison. Still cool to see DOA here although GI is an abomination now.
