Really I just want to program a 3D game but I'm not good at Math…

Also that means I don't know how to make a scrolling game..

Dreamod is making a 3D Scratch, but it will probably take a long time.

Really not many people can make a 3D game.

Scratch isn't focusing on 3D scratch right now, and mods would take a very long time to create.

You'll have to learn Unity3D or Java or something
