My friend came up with this idea but, I just wanted to post it to the canny. It’s just a mall with every item in the store out in like outlets to give it more of an open feel. There could be different kiosk’s for items that can’t really make a store like food. You could get tokens and walk around with some friends seeing what you want to buy. There could be a food court and for exclusive items you could have them only in some stores or just in a specific store in the front for featured items.
TLDR: Rec room mall buy stuff in open stores.
