I understand that the "world first" acheivments may mean nothing to some of us, but it is a big deal to some people. for them the simple enjoyment of the game is not enough. they dont care about story or lore (if they do, it takes a back seat to what they care about more), they are so competitive and the possibility of actually being the first person on the planet to accomplish something really difficult is really attractive. I admire the people that have the tenacity and confidence to actually say 'I can do this; I am dedicated enough and smart enough that I could actually do this.' first lvl 60 or first hc inferno completion is something to be admired, even if its not important to you or me.
