Rose vs Goat: Community Challenge Rewards

I'm going slightly off topic so I will keep it brief. I personally don't see why they couldn't add a few new things every few months. Does the game make so little money that a new map or cosmetic set is too much to make? Specifically on cosmetics, if they added a handful every few months they wouldn't have to drag out the ones they have for so long. They could be easier to get because there would be more to collect in the future. It doesn't need to be a lot. Don't need an Infinity Time mode, Trials of Gnomus or Mystery Portal mode every update. Just something simple. Everyone collecting stickers won't bang their heads against the wall fighting RNG and people will have a reason to keep coming back. I don't know, it seems like common sense to me, but perhaps there is something about the video game business that eludes me.
