Im going to spend 10K Robux to advertise it, and im thinking of maybe 15 - 25 Robux to get the access for the game, please be kind, Thank you for your time, have a great day!
Maybe you should make it paid access for the time being so that it would not get bot-attacked when it is in development and would have many dislikes by the time it is ready. (That is if you get bot attacked) Also some games like Restaurant Tycoon 2 were paid-access when in Beta mode.
Another reason is because they get to experience the game before it is supposed to be released.
You might want to award those who bought the paid access Beta Tester badges or a feature in game as they paid for access to the game. You might want to encourage beta testers to give feedback to your game as well.
Don’t adversite it with Paid access, or most players will not buy it because they don’t know nothing about the game and there is no reputation for it. (You didn’t released It yet)
Usually when games are paid access it means that their are truly amazing to play and have a lot of effort put into them, e.g Vesteria, Wild West, Bloxburg those type of games have a huge amount of work put into them and that is why they are paid access
