Finally my friend and I have completed the normal Titan Quest. We are advancing so quickly through the game, it is scary how much progress we are making.
We managed to defeat the Titan without too much difficulty. Now we are advancing through Act V, and things prove to be a lot more difficult than expected, but once again, we are advancing quickly, as we are already at Medea's Grove.
We should be finished with the game by next week, and then the next difficulty begins.
