I'm working on reaching level 60 as a Barbarian in Diablo 3. I'm currently level 58. Longer term goals include reaching level 60 with all 5 classes in Softcore, beating Inferno difficulty on at least one character, reaching level 40 in Hardcore mode and beating Normal difficulty with at least one HC character. Diablo 3 is more addictive than WoW (or perhaps I'm burnt out on the latter) because the characters feel more individually powerful, the rewards are faster and more randomized, the game can be played in smaller chunks, and solo play is viable throughout.
