Meanwhile the snowboarding is still light years behind Infinite Air, which I think was like $30 at launch.
As for being worth the money as DLC I can't comment on the way others value things but I would gladly pay it but I got the season pass so I didn't have too.
The Alaska DLC is free at least right? I haven't played since probably like January I'm guessing.
