metal gear solid wasnt the first stealth game. there were more. and before metal gear solid there was metal gear games for nes. thats how the gaming industry works. games have to be the same. what are we supposed to have 1 fighting game, 1 shooting game, 1 football game and nothing ever copies eachother. the gameing industry would plain suck. it would be a race to finish a game before someone else took ur idea.
