I first played this game at my neighboors house. The day that I played it, I knew that it was a must buy. Even without the internet, it was tons of fun, and when I got the net, it was even funner. However D2 has some flaws. If you don't have enough ram, it is quite possible that you can die because of time used while the computer thinks. Battle.net on this game is great. Blizzerd made it so there is almost no lag at all when you play. You need to buy this game!
