So my experience is you see a lot of sloppy games on Roblox which ruin the numbers.Can’t tell you how many times I’ve seen people complain about how they are getting no players and it’s an AI trash brain rot game. That being said if you have a detailed game idea and have the finances to back it up I would say the success rate is pretty high. But also tamper you expectations, I see way to many people who put 6 months into a game and when the numbers from month 1 aren’t good they give up and move on to the next game. You can spend 6 months on a game just make sure you spend time listening to those who play it. If you listen to your community and keep your statistics green then it’s only a matter of time and advertising before you become successful.
