I disagree about Sonic Adventure 2, Twilight Princess (especially this), and Brawl.
I can why some might think FF VII is overrated, and Pokemon too (kinda?). But they are amazing games regardless.
FF VII does NOT have a forgettable villain. I'm pretty sure 20 years down the line, you'll still remember him. The cast of characters is awesome, but I guess that is my own opinion. I mean just look at this.
Doesn't this strike as AWESOME to you? (these were made with a 3d printer btw :O)
Also for Pokemon, it's not fair that you refer to the whole series while for all the other ones, they are only single games. Yet your main gripe with Pokemon is that it does nothing new, therefore overrated. But Pokemon R/B/Y did everything new. From then on, every game has been expanded on and brought changes here and there without changing the core of the gameplay.
