There's a lot of misinformation going around about that. Back in the 80s, every game company filed patents for basic game mechanics (Capcom patented character select, SNK patented title screens, etc.) and agreed not to enforce them, sort of like an alliance. They did this to prevent non gaming companies (Disney, Warner Bros., Universal Studios, etc.) from doing it first, screwing the industry as a whole from these features (like the nemesis system). To me, this means only one thing... POCKETPAIR IS SUS!
