My friend and I decided to continue with Titan Quest yesterday, and good heavens did we play fast.
We are already at Knossos after one afternoon's game play. I have never played that game so fast before. Of course our new Epic items helps a lot, but we have a new method of playing which improves the game time.
I give it maybe next week that we finish the game again, also depending on how much we play. If we can do an Act a day, then the game will be completed in about four days.
