Wow....it's a toss up here. I was seriously addicted to 2 different games.
Tie for best: Diablo II LOD & Everquest 2
Worst: Sacred 2 Fallen Angel...I mean this game was a complete waist of money! Would not work no matter what I did to try and make it compatible to win7 and I tried so many tweaks on my pc to try. Just to find out that the makers of the game went under and they had no real support for the game and no real insight as to when if any would be available. And I tried to return to our world famous WalMart just to be told they could not except it due to being opened. Well if I would have know the issues I was going to have with this piece of $h!t game I would have saved the money. Sorry about the rant, but omg don't waist the money on it.
