I agree with everything you said about Helldivers 2. I generally avoid online multiplayer games, even co-op ones, as I don't like playing with randos, but HD2 truly feels like a team effort every time I play, and there's so much variety between factions, enemies, and difficulty, that I am happy to continue playing it over and over again.
Dragon's Dogma 2 has also put its hooks into me. I really enjoyed the first one, and the second one definitely lives up IMO. There are valid criticisms about the frequent low level combat and lack of enemy variety in it, but it honestly doesn't bother me. The more rare enemies show up just enough that I don't feel like I'm only ever fighting low level enemies, and the harder ones are a genuine treat. It's also fun to find a new enemy type that is particularly rare and discover the reason for it is because they will absolutely stomp you unless you're pretty high level. Beautiful graphics, fun world to explore (I'm particularly fond of the caves), and quests that don't hold your hand every step of the way (although, on occasion, I wish they would hold my hand a little more). I do hope they add a setting to reduce the pawn dialog to get rid of idle chatter, but I know the last patch is supposed to reduce the frequency already. I haven't had a chance to test it out yet to see if it's a significant improvement. I also really wish there was a way to tell what time of day it was since you will get missions that tell you you have to do it between certain hours, or worse yet, missions that don't give you a time frame and you just have to stand there and wait. When an in-game day is 45 minutes IRL, that gets old very fast.
Edit: omg, it's the menu background. There's a huge radial clock graphic in the background of the pause menu...
