Hmm that's new to me. For the most part it doesn't make sense since old games are still laying around there and people can get them used for nothing at all. Sony isn't doing it neither is Nintendo.

Sensless. You can play GC games on your Wii and most GC-Games you can buy cheap second hand.

Since you can play gamecube games on the wii, I don't think they'll do it this gen, they are already making from the downloads of the older systems though.

Yes GC games already work in the Wii.  This is what will make downloadable GC games so easy for Nintendo to implement.

Nintendo no longer makes Wavebirds.  The GC Classic Controller I mentioned would get around this.  And the cord on the orignal GC controller is way too short.  Not needing a memory card to play GC games would be another advantage.

Downloadable games are simply more convenient than discs.  No need to swap discs.  Just pick what you want to play from a menu.  Switch from one game to another in much less time (maybe I'm just lazy).  Also, never need to worry about scratched/broken discs.  Plus they can be easily purchased at any time, no need to track down a copy.

I would never buy used gc games. I dont like messy cds

so i agree with the Op

I say yes. I live in Europe where it seems they gave up on Cube early. There is a lot of games that are impossible to find used for a reasonable price because they are so rare. I ended up paying $35(converted from NOK) for a used copy of Pikmin 2. Paying 2000 points for a GAmecube-game would not be problem for me. They are worth it

No real sense to, honestly MS does Xbox originals because they want some more profit off old games cause the only way you get Xbox games anymore is from game stores and they're all used. And used means the store gets the profit not the company that made it.

 Brilliant idea, I'd be all over that.

I would rather them add more 64 games, GC games can be bought for cheap already
