If you are looking for a partner to knock out achievements with, let me know, I'd be glad to help. Also, if you are looking for advice on which games to buy for achievement points, I can help with that too. There are a ton of older games available at stores like Game Stop that you can buy used for under $5. A great place to start is any 2006 sports game.
FYI Avatar: The Last Air Bender is the easiest 1000GS you could ever get. Seriously, it takes 3-5 minutes to get a 1000GS.
