The main reason no one seems to be getting TGF2 is because TGF2 is nothing but MMF2 that is very void of useful features. TGF2 is pretty much only meant for people who are brand new to kliking, and want something nice and cheap, MMF2 is more for people who already know what they want, and they want better then MMF 1.5.
TGF2 is geared more towards TGF users (unsurprisingly). It doesn't allow 3rd party extensions (only certain ones from CT), doesn't have Alpha channels, and you can't do MDI (Multiple document interface I beleive) apps with it.
Besides these key points, it's essentially MMF2 with all it's improvements.
It's the TGF to MMF2's 1.5. If that makes no sense, well, then it makes no sense.
Also unsuprising, is that TGF2 is looked down on, just like TGF was back in it's heyday; though there's nothing wrong with TGF or TGF2, it's all in how you use it.
It won't be nearly as easy for you to nix code from people though, as there isn't the huge backlog of example for TGF2 like there is for TGF1.
