So whatever happened to the whole PGDCE thing?

we decided to drop generics because we planned to bring the engine to developers on older delphi with no generics.

I see. Personally I wouldn't have bothered with trying to support versions that old, but that's just me. I mean, if you can't afford a newer Delphi version, why wouldn't you just use FPC/Lazarus instead? I'd rather quit programming forever than have to use Delphi 7 in this day and age...

You are wrong... Today is still usable and stable. But need developers to mantain it! I think we need to focus on this framework because is simple and very strong.

It's an abandoned project (the developer seems to have just vanished) built ENTIRELY around outdated OpenGL functionality. I don't doubt you get 60 FPS in what are probably relatively simple 2D sprite games, but that's just your CPU brute-forcing the immediate-mode rendering. If you tried to scale ZenGL up to anything relatively complex you would hit a brick wall, trust me.
