(Now that it has ended…) I like your mindset. :) I did the same for the last games I voted for, only selecting less-than-twenty-votes ones (before that, used almost exclusively the Karma ordering).
But I have a question: except for choosing the winners for each category, does the 20 threshold have any influence at all? For example, for selecting games (according to some voting criterion?) that will be featured in a video? I am wondering both out of sheer curiosity, and because mine ended up with 19 votes (lucky guy, there! XD), BUT fared well in the ‘Innovation’ criterion. Does this mean getting a shout-out is out of question or not? Nothing serious, just looking for a clear answer. :)
