We are getting a lot of successful games being remade on modern gaming systems much like movie remakes overtaking the genre.

In both media, I cannot help but feel as if a large cache of material is going unused in solid ideas for movies/video games that were originally poorly executed being revamped in to the entertaining material it always had the potential to be.

So what video games fit this criteria?

What was a great concept or idea or mechanic or plot point for a video game that deserves to be remade in modernity?
