I think the word you are looking for is tiny. I've had diablo 3 for one week to the date. Leveled two characters to level 70, reached paragon level 45, found about six endgame pieces of extreme rare loot. Beat the story mode three times and played the adventure bounties and rifts about 35+ hours alone. I haven't scratched the surface of diablo 3. BUT that is because diablo has been out for quite some time on pc and has layers upon layers of content, six character classes, and depth. Let us pray that Destiny has depth in the base game so that the player base stays on. The biggest concern for me is that mobs are shared and there doesn't seem to be that many. In a game based on leveling by killing mobs that could be an issue.

You did all that in one week?!?!? I think the official bar for a "no life" has been raised.

No life lol. I'm married with a kid, two college degrees own a business and work a full time job too. I work 12 hour shifts overnight and dozing Is allowed. Gives me quite a bit of free time while the boy is in school. Your second character on diablo 3 can be leveled by doing adventure mode bounties.
