Many of the Crash games on this site need new designs, and we're not all artists. Therefore, if you can find/make a good background (and/or site logo) for a game (or the series in general), post it in here and we'll add it if we're fine with it.
In the interest of keeping this leaderboard up long term, I suggest using the admins' guidelines (tiled backgrounds instead of 1080p, no gimmick for scrolling).
