Final Fantasy 7 - The chocobo breeding process is really stupidly dumb/long, even when you know what to do. It's amazing the type of things I put up with as a teenager which just kinda grate now. I've probably invested close to four hours in it already (between catching 'em, stealing the breeding items, racing a bunch, and soft-resetting to get the right genders, it'll probably need another before I'm done). When I first beat Ruby Weapon I did it without Knights of the Round and spent an hour or so grinding it down with Pandora's Box, but now I'm convinced that is by far the best way to get a gold chocobo, at least without outright RNG rigging (which apparently makes it possible to get a gold chocobo in minutes; I should have just done that clearly). Chocobo racing is also a really stupid mini-game. At least FFX's, aggravating though it is, has a strong component of player skill. FF7's is just "wait two to three minutes to figure out if your stats are high enough to win". Fortunately it doesn't need that much investment if you know what you're doing, since you never actually need to race past B rank (which requires relatively little financial investment to get good enough stats to crush).
(If anyone's curious, I'm just doing all this mostly for the science of re-examining the whole process as an adult. I am intending to defeat both superbosses, so the investment isn't pointless, either.)
Super Mario 3D World - Started this, beat three of the worlds. Not much to say, the game seems generally quite terrific. First two worlds are a bit too easy but I'm used to the Mario difficulty curve, and it's already clearly started to tick upwards, so that's nice.
Kid Icarus: Uprising - Holy hell bosses on Intensity 9 are evil. Not that I've actually gotten to many. I'm trying to get through the flying sections with no deaths, then the rest of the level with at most one. I've gotten to a few bosses at 9, but have yet to beat one.
