Current Xbox 360 achievement score stands at precisely 99500. I managed to hit exactly 55555 and 77777 and I intend to hit exactly 100,000 as well.
 
I managed the most difficult part earlier today when I used Watchmen on XBLA to even up my score so it no longer ends in a 1 or a 6. Finished the first level without getting hit for 11 and while attempting that I clocked over 100 thrown enemy knockdowns for 8 more. Couldn't have gone much smoother. Thinking ahead, the only other remotely special scores on the horizon are 111,111 and 123,456. I'll think about getting my stupid 1 back when they come within striking distance.
 
I'll probably attempt to get the 100,000th point on video and I may try to have some friends help me get some 4 player guitar game achievement just to make more of an event of it. 4 vocalists on YMCA seems like pretty good video fodder, but that pops at the start of the song, not the end. I'm open to any suggestions. You guys can see the achievements I'm missing on my account Shaunage and I do have every music game and access to basically everything except 4 drum kits.
 
My main problem with hitting it exactly is going to be Mass Effect 2. It's incredible, but I'm 95% sure that there are more than 500 points between me and the end of the game, especially with 200 or more popping as the credits roll. Going to be a little frustrating stopping near the end to collect people, instruments and a video camera.
 
On the plus side, having been within a couple of thousand of him for the last few years I am probably going to beat Jeff to it. He is also dangerously close.
