since we're all here and it seems we're all in the mood to discuss very important issues, i would like to bring up this tweet that came from the official Uno™ twitter account

honestly i think +2's and +4's instantly skipping your turn make the game more boring and less exciting overall, it adds a certain spice to the game that you can make that random +2 you had in your deck into a +8 because the other ones playing also had a +2 or a +4.
i've always liked playing Uno under house rules, while some of them can be a bit dumb and/or sometimes unfair, i think it does make the game more fun overall
