There are 685 in total, which is interesting because somebody somewhere told us there would be 687. If there had at one point been a Tharja trophy like that special somebody had promised, that would have been taken out for reasons we can’t be sure about. The other hypothetical trophy is a mystery.
We have here a list of every trophy description if you guys are interested. There is no mention of the Golden Sun or Metal Gear franchises ANYWHERE in these, and also notably absent is everyone’s favorite giant space dragon, Ridley.
