Banjo Nuts and Bolts is actually good, plus the Banjo XBLA port is great. Rare isn't totally shit, but I do think that they are the absolute worst developer that has a vocal fanbase (I'd say Sonic fans, but they aren't people)
And while Rare is good on the technical front, I do find it funny that as technology has improved, their games have been looking worse and worse in the art department because they can capture their original designs more closely. It's really a shame.
