Im sorry but portable paper mario and ocarina of time > all
To be honest, that's one of the main reasons I don't like the 3DS. I'm getting a little tired of Nintendo simply doing rehashes of all their most popular games. For me, the best games on the DS were original ones, like Golden Sun, Professor Layton, and Phoenix Wright. My least favourite are ones such as Super Mario 64, the Star Fox DS game (the controls were really bad), and every other remake imaginable.
Since the GBA did the exact same thing (in fact, to a greater extent having both ported NES and SNES games), I've simply grown weary of Nintendo's lack appealing new titles. The 3DS launch titles sure don't look too appealing on original content.
This is though, they release a mix of games. New sequels (New Super Mario Bros, Mario Kart DS, etc), Revamped Remakes (Pokemon Heartgold, Mario 64 DS [even though it was worse than the original], etc), and Ports (Ocarina of Time for the gamecube, Classic NES series, Virtual Console, etc.)
For the most part the vast majority of their releases are brand new games, but they have such a large library of fantastic games, it would be a crime not to rerelease them for new gamers, old gamers who lost their cartridge or whatever, and people who just missed it the first time. Also, its a good way for them to keep a steady stream of releases, as they are quick and easy to make while we patiently wait for the sequels that take much longer to make.
Its also worth noting, that it some instances the revamped remakes are so much better than the original, that its like a new game (See Heartgold, or more so, Metroid Zero Mission).
Lastly, I would just like to state that it could be much worse. I'm pretty sure Square Enix's remake:new game ratio is like 10:1
In conclusion, yes Nintendo makes their fair share of remakes, but that's just because they make their fair share of games in general.
