And that's where a lot of people disagree; I played D1 online a bit before the cheating became rampant; after being forced to cheat myself just to stay alive and not loose all my stuff to noob-killers I played exclusively single player and loved it.
D2... Never played online at all.
Of course both these games are from the dialup era; running a game of 4 people where all are connected with 14400 or 28800 modems... (Sarcasm mode)Those were the good old days(/Sarcasm mode).
I will most likely only play D3 alone.
You mean it is exactly like Diablo 1 and 2? What a shock!
