I think a lot of GAF has the wrong impression of Idea Factory based just on the Compile Heart games. IF is a rather large publisher with a bunch of games in a lot of different genres - most of which we never hear about in the US because visual novels and dating games just don't get localizations.
Personally, I really liked the Generation of Chaos games. I think they are, like, amazing. GoC, for example, is basically a cross between Dragon Force and Dokapon Kingdom, but the English localization suffered greatly from every menu command being a 3 letter acronym, making the game almost impenetrable. But get into the game, and there is so, so much there to enjoy (I would double dip if it went up on PSN, since Aedis Eclipse loses all slowdown when played on a Vita).
