Ah, well I meant the direct DelphiX 'spin-offs'. I guess thats a bit of a vague grouping of these tools, but to me it has always meant the projects that were a result of the "Oh crap! DelphiX isn't being updated anymore. What do we do?!" The answer obviously being these projects that became the 'Post-DelphiX Staple' about 5 years ago. These were the ones that partially inspired and kicked off the evolution of the newer ones in development now.

DanJetX, GLScene, etc are more like 3rd generation game libraries, imo. DelphiX was first and the 'big 4' were roughly UnDelphiX, Omega, PowerDraw(now Asphyre) and XCESS. Actually GLScene is more or less 1.5 generation since I believe it was around post-DelphiX area too. [size=9px](2002-2003 again roughly)[/size]
