As long as people buy them, Nintendo will sell them.
Some games are fun after a long break, I think games that where a lot of fun when they came out are still fun years later and sometimes its like watching an good but old movie again or something.
I for one am looking forward to some 3D remakes of some N64 games, my short list as follows!
1. F-Zero X for the love of god Nintendo.... Please this game was awesome, tighten up the graphics a little turn it into 3D and it will probably suck a month out of my life.
2. I would like to see an all action Star Fox, please Nintendo ditch anything not flying maybe some cut scenes... (I am sure some people loved the tank levels or what ever but I hated it...)
3. I want to see a 3D version of Mario Kart too, maybe just a remake of the DS one with a fresh coat of paint and some 3D goodness.
