Nascar;
But, I reckon someone will flane you, you can make your own threads on the forum, try not to post in other peoples, hence the chances are you'll get flamed.
I'm guessing you are relatively new to this, firstly...
I own 3D game Maker (yeah I know...I wanted to see if it was any good, plus LSD told me to do it) and it came up with good looking results, but the idea is to be creative with preset elements, there is nothing serious with it, and isn't a very practical game maker. Selling something with it would be impossible, the exe made from it take ages to load, the games don't have the qualities you will need to sell.
FPSCreator, looks like a quality and capable program, I don't know much about it, but I wouldn't expect to sell from it. They're really just 'fun software' build games for fun, you will find you cannot make the exact game you want all of the time, features are very limited, I'm afraid there is no way just yet to make 3D games solely by drag and drop software and sell them, if you want freedom in making games and even sell them, you'll need to learn some sort of coding, I think Dark Basic is a really good place to start with that, as if you get anything good worth selling, you can sell it without paying royalties.
If you want to build games for fun, by all means purchase what you wish to make it happen, but 3DGM to me isn't very practical to use and well FPSC has a demo (Download it)
3DGM does come boxed, if you live in the UK you can find it in various shops, and I've seen FPSC in GAME a couple of times. So they're both boxed and mailed to ya
