Just some feedback for why I chose to not purchase the gamepass:
I tend to try and play games the same way a new player or guest would. If I don’t have to buy a gamepass, I won’t, unless I really enjoy the game and feel it would improve my gameplay somehow. I do enjoy challenging myself and experiencing games without the “extra boost” gamepasses may give you. I’m not saying it’s a bad idea to include the gamepass – it’s a great add-on and it’ll be a great way for some extra income! I’d definitely include it as an option for your playerbase. I think a fair price would be 85-250 Robux, depending on tools allowed!
So I believe the way you’re thinking (correct me if I’m wrong) is that you can by the tools individually, a game pass per tool. The way it works is:
Select three, completely free tool options from a GUI of (x) tools, choose wisely, you can’t switch them until next round!
However, if you own the game pass, you can choose four out of the (x) tools. This will give you more of an upper hand. Each tool gives you a certain power-up in game. For example, the Fire-Starter reduces your price to make fires by 50%; the Axe allows you to chop down trees, etc.
