Not only is it too late, it simply costs them money to issue a patch even if it fixes one typo on any platform other than PC.
Yep. It would be a waste of money this far in. It's like paying to put a brand new exhaust system on a car that needs to be completely re-built from the ground up. And I mean every single thing down to the tiniest bolts.
Eventually you have to reach the point where you either accept it for what it is, (a total loss) and put it out to pasture. Or call the scrap guy, and get a few bucks for it.
There's really nothing that can save the game for me, personally. Every now and then I enjoy the first few minutes on the Sulaco, the walk to Hadley's, and the Raven chase down in the hive. But that's about it. Other than that, it stays in the wallet.
