Graphics and engine types aren't as important as how you use them.
Pokemon Black and White got good reviews because of its depth and size. For it to look like Crysis 2, they'd have to sink in millions of dollars that they don't have.
It doesn't matter what you
can do, it matters what you
actually do.
For instance, this is Final Fantasy 7.
And this is Final Fantasy 13.
Final Fantasy 13 can do so much more than Final Fantasy 7 in terms of story, looks, and gameplay. It just doesn't.
Final Fantasy 7 is a brilliant masterpiece of design, because it worked with what it had. Final fantasy 13 is a horrible, linear, straight line with one of the most awful video game stories ever, which constantly riddles its narrative with plot-holes and fills itself with pointless wandering... in a straight line. For hours.
