As charged as i am about the rmah it not the most important feature of the game to me. if i thought the game wasn't for me i wouldn't bother with posting 55 posts a day ..
so what sells me fast paced design of the game from start to farming inferno.. that the game has taken much of the time where your not killing stuff out of the gameplay.. this is actually one of the reason i have played so many games in the past 14 years.many games hit a point where your running around to get to where you need to kill stuff more than you are killing stuff. game get boring ..off to next game.
there how easy it is and will be to level and gear up alts .. there is no assumed dedication to one main..with the shared gold ,stash and crafters ..imake leveling alts quite addictive for a power leveler..and the eventual ability to sell alts means i never have to look at a full list of max alts and delete one .
I am excited about inferno .. because it will be difficult and every mob will have the chance to have a nice price inside.. i can pop into one area kill a bunch of stuff for a wile ..pop into another act kill stuff there for a while and just happily go about my unhealthy number of hours played ..killing and slaughter stuff..
tldr - games sexy because you can always be killing stuff no downtime
