I have 13,000 and I don't have all that many games. My friend rents games all the time so yea, I guess that's why. Oh ya Hawkeye, btw I buy all my own games so don't assume all kids have their parents pay for them lol
I had gamefly for a while which is when I got my current gamerscore (I was determined to beat my friend. I didnt he has like 30,000). I dont really care about acheivments to be honest. I have had Xbox for 3 years and what I have is just what I picked up from beating games.
