I will say that Shadowrun Anarchy is just about everything I actually want in a Shadowrun game, without the mess of rules to wade through. And without people spending an hour planning on how exactly they kick down the door and kill everyone, followed by the hour of people rolling a hundred d6's to resolve it.
For my part, and this ties to Shadowrun definitely, is that I can't stand double-indemnity in resolution. That is to say, if I attack a monster and have to roll against their roll to hit, then roll again against their roll to do damage.
