I want to clear that I don’t think it’s wrong to use premade assets at all, and it’s definitely not cheating as it’s clearly allowed in the rules. I’m talking only about a situation if for example someone got all the sprites from the store that look beautiful and gets the best score in graphics because of that. Are the winners of each category somehow filtered?
Viewing post in Assets from store and rating
Personally, I try to rate games that clearly have original graphics/audio a bit higher than those with premade assets (not that I'd rate those games lowly, but I'd cap it at 3/4 stars for art and audio if that makes sense). I know a lot of other people also give a bit of a boost to the original-asset-using games, so I doubt they'd win in those categories. If they do somehow end up "winning" in those categories then I guess fair play to them
