The game selection is a lot better than the GCN, which is basically standing on the series that already have a fanbase and not really breaking ANY ground with new games, which really seems to have been Nintendo's basic strategy for quite awhile. And sadly, it's been working.
Sorry to jump back to this old point but I just noticed it again and thought since we finally settled (you better believe we settled it) the Sony makes sequels JUST LIKE NINTENDO. I thought I would address it.
On the NES Nintendo introduced:
*Dr. Mario
*Fire Emblem
*Kid Icarus
*Legend of Zelda
*Metroid
*EarthBound
*Nintendo Wars (precurser to Advance Wars)
*Excite Bike
On the Gameboy:
*Kirby
*Mario Golf
*Mario Tennis
*Pokemon
*Wario
*Wave Race
On SNES:
*Donkey Kong Country
*F Zero
*Mario Kart
*Mario RPG
*Star Fox
*Yoshi
On N64:
*1080 snowboarding
*Animal Forest (as you probably know came to US as Animal Crossing on GCN)
*Banjo Kazooie (No longer Nintendo property)
*Mario Party
*Paper Mario
*Goldeneye (no longer Nintendo property)
*Super Smash Bros.
On GBA:
*Kuru Kuru Kururin (Japan and Europe)
*Mario and Luigi
*Mario vs. Donkey Kong
*Wario Ware Inc.
On GCN:
*Pikmin
*Luigi's Mansion
On DS:
*Brain Age
*Nintendogs
*Polarium
*Electroplankton
*Trace Memory
On Wii:
*Excite Truck
*Project H.A.M.M.E.R.
*Disaster: Day of Chrisis
*Wii Sports
So, as you can see Nintendo has been adding to its list of franchises for quite a long time. True, it slowed down during the GCN's lifecycle but it already looks to be picking up steam again on the Wii.
