I used a thesaurus for some ideas and got the following:

utopia
paradise
euphoria (Delphoria... see what I did there )
arcadia

But I also got ravishment, hog heaven, curtains and necrosis - so that wasn't the best way to find a name.

I think it wouldn't be a bad thing to keep DGDev but a new name would be nice.

What about... DelphiPlay?
