Having played Transparent and Baker of Shireton, I expected Fair to be an innovative, environmentally 'busy' game, and that's what I got. In Fair, you play as a self-published author who's been invited to judge an elementary school science fair. The game world is relatively small but extremely lively, crowded with science fair contestants, their parents, and a principal who mostly just wants the fair to be over with so he can set up for community theater rehearsal. As in Baker of Shireton, the world is full of things happening around the player.
Where Baker faltered due to the opacity of the goal (I don't think I'm the only one who never caught on that there was more to the game than unsuccessfully baking bread), Fair shines by giving you a few possible priorities and letting you choose. You don't have time to do everything--will you try your best to judge the finalists' exhibits, or try hawking you book and then award the prizes at random? I played through twice, and I have a strong suspicion that there a lot more possibilities than I found.
A few spots are a little clunky (at one point, you're told the principal is beckoning you over, but given no indication which direction you're supposed to move) but in general the implementation was pretty solid given how many parts are moving at once. Like last year's Midnight Swordfight, a single playthrough is quick, but it rewards revisitation if you want to find everything. Fun and recommended!
