I've always been critical of the various awards out there where people don't need to have experienced to vote (looking at you Oscar's, where people didn't even have to have watched the film to decide if it should win or lose).
There are games on here that I prob would never normally play and now I'm trying so I can vote. Seems like a good idea. In fact I can think of one game I will never own in person but actually enjoy on BGA... Carcassonne. It just works better on here than on a table (my opinion of course)
Flip side, there have been games I wouldn't have normally been drawn to and played on here and now I own physical copies. I get why people are disappointed they cannot vote because games they don't like need to be played on BGA before voting, but it does level the field and ensures every vote given is from someone who has at least tried all the options.
