Imagine you want to create a new team to develop video games. Imagine you have a team of veterans and people with less experience. One of the ways to start is Roblox or UEFN (Unreal Editor for Fortnite).
They are walled gardens but allow you not to worry too much about thinking about the game to develop. Roblox has more players than Playstation and Xbox combined. So there is a solid community of players.
When you start a new project by creating a team of people who don’t know each other, it’s a good idea to start doing smaller tests. So why not try these systems that already have their basis? In my opinion, it is an excellent opportunity to start.
