I finally got a score of 383M in Rocksmith's Guitarcade game "Ducks", thats going to be hard to beat. It's hard for me to get even get near the score, though I score in 100M-200M range consistently. But i have a dream, and that's 999M.
With a lot of effort i finally nabbed first place in Scale Runner too. I think the theoretical maximum is 165M, so there is still room for improvement.
Finally Super Slider is all mine, though the next guy seems to be trying to change that. Playing to level 255 is an affair that takes an hour or so. There is no maximum in this game it's more a question of stamina. Maybe I should target 1000 chains here.
