DRM that takes 1 year to crack is about as good as you can want. What percent of total sales takes place in the first year. If your proposed hacker finds the solution to this one, does that mean they have the general solution? Or does that indicate that this style of DRM in general takes 1 year to crack and is generally valuable?
I know in the indie game field, ~95% of lifetime sales happen in the first year. But to be fair, they typically don't have the similar marketing power as a AAA. I'd venture 60% (gut/instinct). There must be a good reason for running sales even in the long term. That could also be skewed when you think of in-game purchases too. Cheaper year 2 or 3 purchases could be pushed for if they're banking on in-game purchases.
Either way, pretty sure someone broke open an expensive bottle of champagne for a 1 year mark.
