have you guys ever pondered at one game you've played before with a creative gimmick, only to see it used in an entirely different game franchise?

i noticed one with the recent kirby triple deluxe game, in how it shares the same foreground and background gimmick of wario land on the virtual boy

Yes. Sometimes it's so blatantly obvious that you begin to question whether or not they were made by the same developers/programmers.

Donkey Kong Country Returns and Paper Mario 1000 Year Door both had sections where you could go to the background, although only in a few places.

The arcade games Violent Storm and Final Fight are similar in a number of ways.






Doesn't Wade and Guy's poses look the same?
