Howdy DevForum members! I have a empty island and I want to put a shop there! But I am not sure what type of shop I want to put there. I do want to put pets, but I am not advanced enough. I am not sure about adding a tools shop because there is not much you can do with tools in the game I am making. (If you know any good tutorial on how to make a pet system please tell me)
You should add a gamepass shop, or a robux shop where you could add robux bundles, game passes, etc. there 
There will be a GUI shop with coins you can purchase and also gamepasses, but the island will have gamepass prompts next to the shop.
Donation Shop
But personally if you’re not skilled I suggest you to learn a bit more
I know coding, I am just not too advance.
Perhaps somewhere players can go for trading? I think that would be a pretty unique feature, I fail to see many ROBLOX games include that player - player communication at the moment. Regarding your concern on the topic, you’re in the correct place don’t worry. This is a place where players can come to get help on fixing or improving their game.
Definitely would be a nice spot for a pet shop. Have you looked up roblox pet systems on youtube? That’s my go to when learning 
My game does have a lot of player communication, and actually thats kinda the whole purpose. The players have to work together to finish this factory and its like a tycoon they have a factory currency and they need to finish building a factory in a amount of time together and get enough factory currency to go through the exit door.
I have tried, but most of them i have tried to make it usually has a bug I am not sure how to fix. But I will try again today maybe.
Aw that sucks. I hate bugs. Fingers crossed you find a way 
Seems like a small platform, maybe something like a little neon, colorful, vending machine for some sort of in-game item or prize?
