We Are All Achievers
We are all achievers. Games just don’t always provide us with sufficient metrics to measure our achievements in spheres other than ‘how many mobs have I killed?’.
If you have ever run close to an enemy town in WoW to fill in that last bit of your zone map, you are an explorer achiever.
If you have ever looked at the size of your guild, or your friends list, or counted how many ‘hellos’ you get when you log in, you are a social achiever.
If you have ever looked at a PvP leaderboard to find your position, and attempted to raise your position on that leaderboard, you are a killer achiever.
Given UI feedback, every playstyle can be supported as well as the traditional ‘advancement’ achiever playstyle.
