Edit: Staff said you are allowed to add it to your list. They'll decide on a case by case basis if it actually makes it on the community list or not (definitely needs to have enough votes). If you want to add Blood & Wine to your submission, just add The Witcher 3 and they will get what the vote is for.
Original post: The year is pretty much done and I can say that, without a doubt, The Witcher 3: Blood & Wine is one of the best things I've played all year. There's a little problem though; it's an add on for a game released last year and requires that game to play. So some pretty big knocks against it, BUT it is bigger (and I'd say better) than most games. To me it feels on par with an Assassins Creed game in terms of content, plus it features a brand new map/world to explore. Saints Row 4 couldn't even muster that up, and it was a $60 box product (side note: Blood and Wine was 20 bucks on release. Pure Insanity).
So yeah. I feel passionate that it should be allowed for the community list. I don't think it has a chance of making the staff list because most of them haven't even finished the base game, but I feel like there's a decent number of community members who feel the same way as I do.
