I think that's like a lot too high, but I guess it has done quite well.
Maybe that was the fanboy in me speaking, lol. I'll go with 350k. Anyway, about 10 people i know have got this game and it already have 9k reviews on XBLA. Oh, and its good that XBLA games now have 400G instaed of 200. I got 300/300G in the first one
Anyway, Im downloading it now and i cant wait, Trails HD was my favourite game of all time!
