I've been deeply enjoying Breath of The Wild. It's my favorite zelda game, and it's my favorite open world game.
And it's odd, because there are so many areas I can find problems. Chiefly the variety/difficulty of enemies. The game does an excellent job of giving fair and incremental rewards for exploring, but to a point where I'm actually torn about getting stronger. I don't want the "endgame" to be too easy. Unfortunately I pinned some of my hopes on Master Mode ("hard mode") but it just made enemies aggravating (higher health & regen, testing patience more than skill).
It's also odd because I'm truly not a huge zelda fan. I've always found the dungeons to be a bit more tedious than rewarding. And the combat has never really stuck with me (honestly I enjoyed Skyward Sword's the most because of finally-decent motion controls, but that game's world was gaaaaaarbage).
It's the first open world game where I look at the map and my heart goes just a bit aflutter at how many things I still want to explore (easily my favorite part was trying to find the "memories" via pictures of a scene and trying to triangulate the distant landmarks to locate the spot). Nintendo let the writers run with the written dialogue instead of just translating; I can't even think of a first party nintendo game that comes even close to being as fun to read (the downside is that the cutscenes have dramatically worse writing and it's a very noticeable drop in quality). And the game is overflowing with mechanics.
It's also really accessible, which usually doesn't mean much to me but my GF is also loving it and is having such a different experience than I am (this is one of her first dual-stick games so combat is tricky, but I'm actually kinda envious of her because I think she's not going to feel conflicted about getting as strong as possible before the endgame). It's honestly very gratifying to talk to her about this world we've vacationed to separately.
The context for what makes a game a "perfect" game to me is generally superb execution on a strong and easily-definable premise (Super Meat Boy, Civ4, Herzog Zwei, DOTA, Dark Souls, Megaman X...). "Open world adventure" has always been vague to me, to the point where I pretty strongly felt that there's no way to perfect a concept so abstract. And yet, I feel like I can hold the idea of a perfect open world game in my head, and it's this game with just a little more...
It's an imperfect game that I can't give anything but a perfect score.
