Diablo IV is having its first free non-beta weekend.
I got a level 12 Druid so far, going to take it 20. Opted for the Lightning build, its pretty fun, reminds me of Sorcerer some since I did Lightning Sorcerer in the open beta.
I'll buy this game someday just for the campaign when it hits the 20 dollar bin, I'm in no rush. I waited 5 years or more before I bought Diablo III and played the campaign, glad I waited that long really, it was very nicely polished and gave me an excellent short and sweet single player experience. endless grinding isn't my thing. learned my lesson on that in 2005 in WoW. life is too short for endless grinding.
