It's funny how the Xbox gets off the hook in this discussion. That system died about the same time the Gamecube did. And with no "killer app" like Twilight Princess in December, either.
Does anyone think that Xbox owners got jobbed? After all, there is no gaurantee that you can play any of your games for the 360, since even the supported backwards compatible games sometimes aren't emulated correctly.
You also can't use your Xbox controllers on the 360.
The Wii has true backwards compatibility and you can use all your Gamecube controllers to play Cube and VC games.
So, as an Xbox and Xbox 360 owner, do I endlessly whine about the Xbox getting jobbed? No. And you can make the case that I have even more of case than mad Gamecube owners.
I don't whine because I understand that the system's life cycle is over. It happens. It had a nice run, but it's done. Ditto with Gamecube. I don't hold it against the company. Especially when a system had a variety of excellent games, which an unbiased, objective review would reveal the Gamecube AND Xbox had.
If you really want to expand your library, buy a GBA player for your system, it'll expand your library to about twenty gazillion games. Most of which can be had for less then $15 bucks at the local Gamestop.
