Sometimes when I'm experiencing a world for the first time, I like to be a lone wolf and do it alone. I think it's the fear that the other people I'm playing with are going to rush ahead, grab better gear, more currency, etc. before I can. But I hope Bungie finds a way to eliminate that feeling in Destiny so that you genuinely want to spend time with other players from the get-go. However once I've gone through a game, I love joining up and helping others. The example that comes to mind is playing Journey on PS3. Depending on my partner, I didn't like playing through the game with others the first time through. But once I got the white robes and felt like I knew all the nooks and crannies of the game, I loved trying to be a help to other less-experienced players. Guiding players off the beaten path to find glyphs and unlock achievements was lots of fun. I can't wait to see how people work together in Destiny. If there's any developer who can solve the common problems in the co-op experience, it's Bungie.
