I didn't make this page, but I think that Letter Grade at the End of a Level should be renamed Letter Grade, with the alias Letter Rank. The distinction between grades that appear each level and those that don't isn't quite meaningful enough to justify a separate page for either. We needed a generalized page for letter grades anyway.
Infamous 2, at least, is still entirely worth playing. Even at the time, it was more consistently enjoyable than the first game because it smoothed out so many rough edges. I'm sure age has done no favors for Infamous' jank.
