People always edit my templates

What's wrong with that, as long as they aren't for profit?
I know there are a few variations of some of mine out there. I'm flattered that people like 'em enough to modify them. I think modding game stuff, no matter if it's covers, Gameboys, arcade cabinets, or whatever is one of the best parts about the hobby

since they are so good they are able to be edited in many different ways 
Yes, this! Doesn't mean you did it wrong, just that other folks may have a little of their own flava to add to it

I totally dig Autobot's blue/purp spine logo on the SNES template of mine that he modded.
