Halo 3 was back in the UK top 40 this week. Seems to pop up there fairly frequently from time to time IIRC. And again, was in the Amazon top 100 last I looked. Just think that in 2013 when Halo 4 is coming out, Reach will still be poping up in the charts.
And I forgot, it's also on games on demand, so has sold many that aren't counted at retail.
