Would I EVER be able to create a Final Fantasy VII Kinda game??

Not that I know of.

Let's see.. you'd have to design 3-D areas, 3-D monsters, 3-D spell effects, 3-D characters + animations.. you'd have to be great at 3-D modeling / animation, for sure. (Unless they come with crappy stock characters.. but people would rarely use those.)

I seriously doubt one like that would exist, except maybe as a development kit or as the game engine itself. And those would be SERIOUSLY expensive...
