> If no other DRM has withstood for 300+ days before being cracked, then it seems pretty useless.
Based on what?
I'll wager that if a DRM is un-cracked for just 15 days it's already worth it. For most video games, the first few weeks after release are where a huge proportion of the sales are done because no one wants to wait to play an hyped game.
If you can keep the game uncracked for those 2 weeks then a lot of people that might have downloaded the cracked game will just buy it because they don't want to wait.
