How much would you pay for this concept for a "Light" Delphi Edition?

[SilverWarior]

FastMM on the windows platform aside (are they still using that?) the Delphi compiler should be producing faster code which for certain CPU heavy games is always desirable and with IOS/Android devices it might even be essential in a small number of cases.

Yes Delphi is still using FastMM (striplined version but you can always download full one from FastMM webpage).

As for MacOS, iOS and Android in the future, they are using new compiler (LLVM compatible) with Active Reference Conting. I have seen lots of complaints about ARC implementation in new compiler as it causes significant slowdowns, especially in multithreading applications.
Also some pepole say that there is a need to change lots of code for it to work OK with this new compiler (weak referencing, implementing of new DisposeOf command for destroying objects in some cases, etc.).
Now I stil haven't done any tsting of this new compiler so I can't talk from my expiriences but from what I have read around the web it seems that Embarcadero maybe hasn't thought that through a lot. And what is worse it seems that Embarcadero is not realy prepared to listen to comunity suggestions on this matter (had seen a few flamewars on this matter).

Obviously somebody there thinks their compiler is superiour or it's continual development over a switch to FPC is foolish. So some clean hard facts about why the compiler is better than FPC, performance, stability etc would go a long way to improving the image.

You have to understand that Embarcadero spent several years in developing of their own cross-platform compiler (currently only supports MacOS and iOS, but support for Android and Linux si planned) so it would be folish of them to just throw away all their work so far.
Now I don't belive that at this stage their compiles can even compete with FPC one but in time this might change.

I will settle for nothing less than the total dominance of Object Pascal in the gaming industry with the secondary objective of crushing C++ into the metaphorical dirt from which it rose.

Then I must dissapoint you. You see the Embarcadero isn't only developing Delphi but is also developing C++ Builder so no the C++ won't be crushed into metaphorical dirt.

I would one day like to release games for the PS4 and XBox360*2 (or whatever they're called) in a legal way. For various reasons Sony and Microsoft are unlikely to ever allow FPC compiled submissions. Em. are our only hope of having access to platforms like these in the future and indeed as yet unknown platforms with locked in commercial style development pathways.

I may be wrong on this but I think the main requirement from various platforms like PlayStation XBox and others is automated garbage colection to prevent Memory Leaks to cocuring as the OSes on theese platforms are not so fool prof for running out of memory.
I think this is also the main reason why Embarcadero is developing their own compiler which has such system already built in.

And versioning (fragmentation of Delphi users over umpteen versions) is one of the worst problems of Delphi.

I must agree with you on this.
