I don't like to consider myself "the best" on any games I play. It's not like I'm in a competition. I go at my own pace. I always start the game on Normal difficulty, try to accomplish the challenges, try to discover everything, get the rest of the trophies after I complete the game... I'm not in a rush to be #1. Although, I have a pet peeve: try to complete the game with no deaths.
Now, when I see a game I love for some reason, I try to push thru the limit. I always loved to kick ass in MGS PW Versus Ops. I won a lot of games, but I got beaten so many times. But there was something on the game that kept me playing, not caring if I was gonna lose.
And when I bought Ground Zeroes recently, I decided to go for the Longest Headshot distance record. I did manage to reach #1 worldwide, but others beat my record in less than a day. But I already got to the top and took a picture of it as evidence. I don't need to prove anything else.
