1 Sonic the Hedgehog having a main protagonist who ran so fast that the screen itself could barely even keep up with him (Super Mario Bros.)
Since when did that concept ever apply to that overrated plumber? Plus, the looney tune's roadrunner had this concept before there was any video game. As for Crash Bandicoot ripping off Mario, you do realize Mario did not invent the most general concept in platforming, right? Haven't you heard of Sinbad the Sailor?
