Keiji Inafune Working on Level-5's Guild 02
Sequel announced before Guild 01's release.
Before Guild 01's release, Level-5 has announced a followup. This week's Famitsu has first details on Guild 02.
According to Sinobi's quick summary of the magazine, Guild 02 will feature contributions from former Capcom great Keiji Inafune, Mini Kitchen's Kazu Ayabe (My Summer Vacation series) and Takemaru Abiko and Kazuya Asano of Otogiriso fame (a summary of this CunSoft classic here.)
That's all the info contained in Sinobi's Tweet about the game, but we'll hopefully have additional details later. We should also be getting a review score for Guild 01, which sees release next week.
