I've been diving back into Ghost Recon Wildlands after discovering just how damn enjoyable the game is at the highest difficulty levels. Suddenly sniper rifles and stealth are the only viable playstyles, and I feel like I'm actually being tested by the AI rather than watching all these paper narcos obligingly fall over and die for my amusement. I also love how unwoke the game is. Very America Fuck Yeah.
I also dusted off Master of Magic. Still haven't found a 4X that rivals it in my eyes, and it's not nostalgia talking. I actually never played it growing up (though I played MoO and MoO2 like my childhood depended on it). Good shit.
There haven't been many times I've sat down to play something in the past 25 years where I didn't want to play Master of Magic or Master of Orion 2, so I commend your choice, OP.
I'm working on Sunless Sea, which is alright but it takes some time to get used to the pace and slow-burn style of story progress and creeping dread. I'm waiting on Sunless Skies to hit consoles soon.
I did try the Avengers beta, and it's nice that every character plays differently and mostly reminiscent of other franchises with each character, but I'm not feeling the gear-dependant power levels aspect.
