But I have more games that I haven't earned achievements in so tack on maybe 10. --- After some searching today (7-12-14) I found the first post I ever made on GFAQS :) http://www.gamefaqs.com/boards/957985-dead-rising-2/66994453
About 210 (including ones I removed record of since I had 0 GS).
I completed 42 of those, counting achievements...I've actually 'finished' more (RDR; Tomb Raider; etc.) but don't count them since I haven't finished the whole gamerscore...anyone else count them that way?
