I don't think we need a lot of general OOP tutorials. That is allready covered by some other sites, most notably: www.delphi-basics.co.uk and delphi.about.com.

What we do need is some extra beginner tutorials that really focus on game creation. There used to be a lot of delphix tutorials (I collected those and learned from them), but DelphiX isn't the future. We need toturials that explain more modern libraries like Andorra, Phoenix, HGE etc..

I have no experience with these libraries because after I learned DelphiX I started to write my own engines. The only thing I could do is write something about OpenGL, allthough that's not really material beginners should look into.
