I agree. Not to mention that many of these "original game ideas" are just re-workings of the Oddysee/SligStorm idea! I had to do Oddworld Party because I felt that the Fan Corner was full of platform games
.
I have two questions all aspiring game designers should answer before making an Oddworld game;
1) Does it really have to use the established Oddworld main characters and locales?
2) Does it really have to be a platformer? Why not a FPS or turn-based?
