More Details on クロスエッジ / Cross Edge / XEdge, the newly announced PS3 mixed franchise RPG are provided here by Famitsu. When I first heard of this game, I was sceptical, and seeing those screens (which look distinctly PS2 in calibre), and also hearing the somewhat mixed reception in the Japanese blogosphere has done nothing to allay my concerns, even if it does include Etna.
Including a bunch of popular characters from a variety of games and then letting the player dress them up might cut it for a dojin game, but my suspicion is that such a pastiche of characters will not result in a rewarding story. Perhaps it could more accurately be thought of as charcter goods. Still, it remains to be seen how this will turn out; the developers involved can hardly be keen for their characters to be involved in a licensing debacle (or can they?).
