1) Technically speaking, Team Fortress 2, which I was playing with friends, but I'm not going to count that because all we ever go is play what is functionally, though not necessarily literally, rocket-tag on an all-crits server. It's fun, don't get me wrong, because a lot of stupid stuff happens on all-crits, but I don't really think it counts for this discussion because I played it "casually", for lack of a better term. Also discounting visual novels; I love Grisaia no Kajitsu, but it's not much of a "game".
So, with those conditions out of the way, I've been playing Hyperdevotion Noire: Goddess Black Heart. It's a spinoff of the much-loved (by me, at least) series, Hyperdimension Neptunia, which stars the supporting protagonist, Noire, rather than the main protagonist, Neptune. It's the first game in the series to do something really new since Hyperdimension Neptunia: Producing Perfection, which was an idol-management game, and while I love all of the improvements that they made in the PS Vita Neptunia Re;Birth sub-series, those are just remakes of the first 2 games. The first two games really needed the improvements, but they simply use the battle system from the third game, Neptunia Victory, with the story and characters of the game that's being remade.
Unlike the other games, Hyperdevotion Noire is a strategy RPG. It works pretty well, all things considered; the Lily Points system is interesting, and the characters, stages and gimmicks are varied enough to stop things from getting boring. It's goofy, as well; one of the mage characters has an ultimate attack, known as a "special move", called "Cosmic Banana Rain", wherein she conjures a magic circle in the sky from which bananas fall onto all enemies within range. It's pretty powerful, and it's got a huge range and AoE. "Fill the world with the fruit of life", indeed. Regardless, I'm enjoying it quite a bit, though I don't like how you can't buy any weapons for any of your characters, except to four of them, so you have to craft them from items, but that's not a huge deal.
2) There's a level in Hyperdevotion Noire wherein there is an army of zombies, spiders and Pac-Man ghosts (yes, actually) that you need to exterminate. However, at the same time, the zombies can turn your party members into zombies, and if all of your party members become zombies, you lose. Additionally, there is a line on the map that you have to protect; if an enemy gets past your characters and enters the line, you lose. It's not particularly bad, despite how it sounds, once you get past the fact that the Pac-Man ghosts can petrify your party members, rendering them invincible, but totally useless. Even worse, their petrification attack is AoE, in a large rectangle in front of them, meaning that they can petrify multiple party members in a single attack. Thankfully, one of units in the game nullifies petrification if she's the Leader, but that doesn't change the fact that the ghosts still do a ton of damage with their petrify attack, and the game's mechanics strongly encourage bunching your characters up by increasing damage and lowering skill costs when characters are standing adjacent to each other. It was tough.
3) I'm looking forward to a whole bunch of games, though I can only think of a couple off the top of my head. One of them is the next version of BlazBlue Chronophantasma, because I want to play as Lambda again, and I want to see if they changed her Sickle Storm and Spike Chaser to be the same as Luna-form Nu's, because those versions suck and I hate them and I just want to do all of my awesome sword combos again like I could in Continuum Shift Extend. ;-;
