I got surprised that most of them are, if not good, at least tolerable. However, there are a few themes I have doubts about.

* Change the genre of a classic video game *

How can one do this without breaking copyright laws? Let's say I want to turn Pac-Man to a platformer. Clearly I cannot call it Pac-Man or use the pac-man character in the game. Should I just replace it with, say, a dog, pills with dog food and ghosts with something that eats dogs?

* Color changes everything *

What if there are people who cannot see colors properly (e.g. due to color blindness), wouldn't this be a little bad theme for them?

* Tiny town *

Didn't we have something like this just a few LDs ago? (It was small world or something).

EDIT:

* Limited memory *

A DOS game?
