Why a GBA port and no GC port?

[Ze_ro]

the highest-rated third-party GC title is Rogue Squadron II, ranked 51st. And there are only four third-party GCN titles in the entire top 100.

So, Nintendo has released 96 titles that were better than pretty much everything else? I can't even name 96 Nintendo-made Gamecube games. Where is this information from?
