To be honest, they won't. Every single PC port had their good share of problems and I knew that when I pre-purchased FFXIII but to not be even able to start the game with my high-end computer is bulltrout. It means they didn't even try to fix the most basic problems of the port. They just went the easiest possible way to get a lot of money.

Surely you would be angry if you bought a cheap PC that you had to repair for it just to work even though it was advertised as fully working machine right?

I am pretty angry about this, I am really only not making THAT much of a scene because I don't have time to really play the game much for the time being so I hope that they release patches in next two-three months so the game actually works without me having to use 3rd party programs just to play it.
