I, as many of you guys know, love Nintendo with every bit of my soul. There's a reason: I have never played a bad first-party Nintendo game, especially in modern day. I have played mediocre Nintendo games, but never a bad one. Think first party for this. From Nintendo and studios Nintendo uses directly, such as Game Freak.
In my lifetime, I have preordered numerous games, the most recent of which was Majora's Mask for 3DS (normal edition, not the limited one that sold out). Of all the games I've preordered, the only ones that weren't glitchy messes or broken upon release were Nintendo games. I preordered both versions of Smash Bros., both of which were amazing upon release, only needing a first time update for online play.
Any other company I have ever preordered from really messed up. Watch Dogs was pretty mediocre as a game, GTA V was glitchy and the online was broken for a few days due to server overloads, and Skyrim was a mess upon release. Skyrim is one of my favorite games ever, only beaten by Persona 3/4(Golden), EarthBound, and Pokémon Emerald, but it was really glitchy, and still is.
tl;dr Nintendo is my favorite and I'm expressing favoritism.
