Startup Idea : Game Ladder

Everything is better with competition. When we talk about games, everybody wants to compete, win, and be better then your opponent. The problem is: some games does not have a rank or a ladder that u can see people whos doing better then you..or that you would love to challenge...What if there was an APP that could register and give you some kind of pontuation for every match you won in your favorite games? Like card games (magic, pokemon, yo-gi-oh...) or even live games (chess, ping-pong, beer-pong), group matches (football, soccer, you name it)...The app could socialize people that could interact and match it up some battles to climb even more in the ladder system of his choice...!
