Kid Icarus, Mario Kart, the announced titles coming this year (though those are unreleased), Samurai Warriors, Overclocked, Tekken...there are actually quite a few good 3DS games out available, not to mention the e-shop titles (not counting VC and DSiware). Not a plethora, but there's enough for it not to be considered crappy.
Also, regarding the topic, personally, I wouldn't buy this game until it gets cheap, seeing how much of a pure remake it is. However, this is because I've played 64. If you haven't played 64, it's worth it; however, if you have played the original I'd suggest waiting for a sale or price drop.
