So I've tried Paladins recently, and it's like Mario Kart as a fps. I mean they had some liberties when designing characters such as a giant turtle, King Bob-omb, a midget controlling a giant robot, they even have characters with pointy ears wearing dark outfits.
My favorite feature is when you knock out someone it shows their name and it's perfect for out of context screenshots.
Main flaw: There's no great variety of stages or maps.
Hate to bug you, but I saw your SMBX post with the custom sprites, I think I get a basic idea how to make them, simply replace the sprites in the template with your own(?), my question is, how do you add them to a level
