I grew up always being on soccer teams, track in middle school/high school and wrestling all throughout high school. And now that I'm done with all that I use fighting/shooting games to please my competitive side =)
It's something I could practice and strive to be the best at in the comfort of my own home, online or with my equally competitive friends. Taking wrestling to the next level would be making it my life. This is just a hobby on the side that still feeds my competitive spirit through owning people online, or going to tournys.
That's just me though. Or is it? Anyone else like competitive gaming because they use to play sports on this forum?
