Just get a Wii or Wii U, they're probably cheaper and have a much wider library.
EDIT
Oh, the games? Out of print, get lost and destroyed over time. Nintendo isn't particularly fond of rereleasing its titles, and the fact all of its systems are gimmicky these days makes it difficult to do so. So you gotta pay top dollar for a copy that's still functional or go without.
Still got a copy of Luigi's Mansion I play once every October (until Sir Weston refuses to cooperate and I get fed up) and the Ocarina of Time bonus disc that came with Wind Waker. Unfortunately my copy of that's no good anymore.
