Ok ok let me revise it again:
- Retro Studios (Metroid Prime, DKC Returns, some Mario Kart 7 tracks)
- Intelligent Systems (Paper Mario, WarioWare, Pushmo, Super Metroid, Metroid Fusion, Metroid Zero Mission, Fire Emblem, Advance Wars)
- HAL Labs (Kirby, Super Smash Bros.)
- Project Sora (Masahiro Sakurai's joint venture with Nintendo, created Kid Icarus Uprising)
- The Pokemon Company
- Game Freak (Pokemon main seiries)
- Monolith Soft (Xenoblade)
- EAD (Mario, Zelda, Donkey Kong, etc.)
- EAD Tokyo (DK Jungle Beat, Super Mario Galaxy, Super Mario 3D Land)
- Nintendo Software Technology / NST (Mario vs DK series, Metroid Prime Hunters)
It wasn't supposed to be a complete list of every single game they made. Sheesh. You expect me to be that diligent?
