I think I spent a lot of hours in the last weeks in DS.
I played it the first time by a friend in 1-1, without the training session.
The first thing I learned in DS was how to move, block and attack through the instructions of my colleague.
The second thing I learned in DS was, how to make my way back to nexus without my body ;-)
No, really, DS is in my opinion the greatest game I ever played.
Sure, if you defeated the game around 20 times, it is not the same feeling like the beginning, but I have several things to do left.
So many weapons I never tried, so many fight tactics I never saw before (in PvP), so many new friends with which you can run through the levels.
