I also bought the book+demo, and on startup, it downloaded all standard objects from clickteam, and installed them. I really can't see why the TGF2 extensions would be any different from MMF2's extensions, if TGF2 is just a stripped-down version of MMF2. I dunno.
Wouldnt that kind of be a step back from the original TGF though? Perhaps they should add extension support, but limit it to what program languages can be read after its compiled into an actual extension. Perhaps limit the power that a TGF2 extension can perform... they did it with TGF to MMF, why not keep that same limitation live?
I think CT will be able to create extensions for TGF 2, just they get to control which extensions are for TGF 2... It is just that a third party can't directly make an extension for TGF 2, without CT's say so.
I imagine that the extension set for TGF 2 will still be limited compared to MMF 2 standard, so I advise everyone to buy MMF 2 standard or atleast try the demo and see which is right for you...
remember that TGF 2 can't even do alpha channels... It is meant to be an introduction to click products, so if you are already into them, then there is NO reason not to get MMF 2.
What functionality are we losing however, if we just get the standard copy of MMF2, and not the Developer? The whole royalty thing is understandable, but I dont want to lose out on major features I've been waiting for, just because I dont have $299 right off the bat.
