Hi everyone. I have two teenage boys who are obsessed with creating realistic trains in Roblox. We live in Japan so train culture is very prominent. They have spent over 500 hours designing a massive world with trains and buses, but it all belongs to Roblox doesn’t it.

I think they have a lot of talent and want to give them an opportunity to develop their own game. What platform would you recommend they start out in? Thanks for any advice,
