The idea is to get a group of experienced gamers to list their favourite games in certain genres or by certain designers. That is, to compare apples to apples (as opposed to comparing wildly different games to each other just because they were published on the same year).
Which are the best train games? Which are the best light fillers? And so on. It’s not another award, just a way to get a bunch of interesting top lists. The results are published in a blog piece by piece, but it’ll take a while before anything comes up — the nominations just began.
