Steam still doesn't have its fucking servers up to where it can handle everyone at the steam sale. Had to restart the client several times just to get the store to even respond, and it still freezes randomly. Simply logging in online at least gives you the option of closing the tab when it breaks.
Now for some of my recommended games right now:
A Hat in Time:
Solid platformer, collectathon, adorable characters, good story (although short), and pretty mario-galaxy-esque graphics.
Earth Defense Force:
Takes all the good things about Starship Troopers and throws it into an anime setting, and then into a fight-the-horde game with giant insects, robots, spaceships, spiders, hornets, more robots, and also giant leviathan bosses sometimes. Upwards of 60-100 weapons for each class that scale in difficulty and stats. 80 missions in the vanilla version of the game. You might think its overpriced at 20$, but its normally 50$, so I highly recommend it. Up to 4 player coop against the invading creatures, and friendly fire is always on.
Devolver Digital's take on cyberpunk settings, Ruiner is a run and gun, almost-bullet-hell fighter, where you use combinations of dashes, guns, melee attacks, and other perk/skill tree based tactics to cut down enemy after enemy. With the silent protagonist role turned up to 11, and the tropes being piled on, its got an unfortunately short but intense story. Also the difficulty amps up considerably from start to finish. Also has a skillpoint system you can completely switch up at any time, and you get more through out the story to then spend on skills and tactics to assist you in combat. Oh and the soundtrack is perfect for the game.
