Yipee! I made 500k in Geometry Wars today! (540k, actually), getting me 6 out of 12 acheivements.
This means I can seriously consider giving it up. Maybe. Next reachable target is Brian Sharp's high score of 650k, who's the only person above me on my friends list. After that, next acheivement is 1,000,000 score, or a few others that seem far from reachable.
(Yes, I know there are people that score many many millions. They are young. I am old. Don't bug me. :-)
