I've wondered at what motivated that design decision. Gamer culture (or the gamer culture I come from) was always about isolation and personal enjoyment. You might compare notes with a friend at school or work, but game play with other people was generally competitive, not co-operative. When did all this sociability become popular, and what drove Bungle to design their endgame around it?

Console gaming was at first more of a solo experience, except for some games with co-op and of course split screen multiplayer. On PC there have been numerous online games that while not requiring players to interact to complete anything, were always beneficial to have extras. While I do enjoy a single player game as much as I always have, I find nothing wrong with online games that take this approach. That may be because I've played them since games like Ever Quest and etc. though.

I suppose it comes down to personal taste then because I never enjoyed those online PC games. The feeling I get when I see 'Someone invited you to play Destiny' is the same one I got back in the day when I got LFG messages on Everquest and the like: annoyance. It always felt intrusive.
