does anyone has suggestions for good free 2d and 3d game engines that dont need my email to use.

I have an idea for a new game but can't decide on an engine

The engine will depend a lot on the game you want to make. Having said that, I can highly recommend Godot, it's free, no account or email, and you could make pretty much any game in it. There are also plenty of tutorials online now to learn the engine! 

Godot, the 3D is not as robust as say unity and unreal, but still adequate for indie devs.

(moved to the right category)

If you are new, I recommend you Godot engine. Its easy for beginner. If you are more professional i recommend using Unreal engine.

Hope this useful for you .^v^.

For visual novels, Renpy is pretty good too even for beginners
