The original revision of what is technically the third game in the storied Guilty Gear franchise, and the one that Arcsys is continuing to update, tweak, revise, and add to more than a decade later. That said, it's a pretty solid base to build off. This is the entry that brought in fan favorites Bridget and I-NO, and it doesn't skimp on the extras, either. It's been surpassed by the later releases, but it'll still do in a pinch if you need a Guilty Gear fix.

International releases got the pointlessly-changed title Guilty Gear X2.
