I'm pretty decent at racing games, but my real forte are sports games. Not only have all the Platinum trophies on my PS3 come from a variety of sports games, but I was heavily into competitive play in the NHL series back around high school. At one point on NHL 10, I was in the top 75 in Canada, and I logged well over 1000 online games the year after on NHL 11. And then last August, after having not playing NHL online for 2+ years, I managed to beat someone in the top 1000 in the world in my first game back, ending their 18 game win streak.
I know a lot of people aren't big on sports games, but especially when you get into the competitive side of things, they're a lot tougher than you think.
