Nothing to do with me being a nintendo fan, still.
It's about you.
I'd also like to point out how it's impossible to be unoriginal for using your own concepts.
Nintendo comes out with Mario Kart
Sony comes out with Uncharted
Nintendo comes out with Mario sports
Sony comes out with The Last of Us
Nintendo comes out with Mario Party
Sony comes out with Infamous
Nintendo comes out with Mario Galaxy
Sony comes out with God of War.
Over 100 games involving Mario can't get anymore unoriginal than it can get.
