There are multiple games I'd love to see reimagined. I mean, we know that there were some games way too late for the 3D transition, but if the programmers are good enough, they can make a game just like it was in the 1980's. You know...but with polygons. I never played any Punchout game, but I compared the games via YouTube, and they look quite similar to each other in gameplay.
A game I would like to see have a reimagination session would be Ice Climbers. It was a bit difficult on the NES, but I'd love to see a remake for it. I wouldn't care if it would be 2.5D, I want to see a remake for it, However, it would have to be in 2.5D, because of how the game is played. Then again, Excitebike 64 made a 3D transition while keeping to the formula...
