Not bad, this would definitely bring some fans/players back to this game. The perfect fanservice for this game would be if they'd add team battle mode outside of tag, momiji and rachel or momiji and leon should be the first two dlc characters that they'd release for sp2, then two guests (Tifa and Kiryu would be nice) and at least 4 stages, kyoto in bloom, aerial gardens and 1 stage from DOA2 and 4 imo.

They'd probably charge $200 for that XD.

4 retro characters and 1 costumes pack is totally worth what we had for SP1, I believe (2 costumes pack and 2 guest characters).
