Submarines are fucking useless
Nobody asked but I found out this was very very wrong.
Boomers are extremely frightening. You have to use them thoughtfully, but their survivability is a huge advantage even in a game where MAD definitely happens because they ARE super exposed to a random destroyer or sub killing them but are effectively, if you shoot and scoot, immune to counterforce. With MIRVs you can just pepper a whole country with impunity. I've even had boomers (on my custom maps) take world voyages restocking and hitting stuff all along the way.
Regular subs are actually the sea apex predator, but so it basically comes down to a circle of cruisers being dedicated destroyer AND shore bombardment killers, destroyers being sort-of sub killers and air killers, and subs being destroyer and cruiser killers. I haven't tested it yet (it's not in Blitz mode), but I think cruise missile subs are probably optimal for the boomer version of reducing enemy defenses like SAM sites, stuff you can't afford to waste nukes on but that would otherwise ruin your own strike.
I've been playing a lot of Easy Red 2 and some Nebuchadnezzar.
Easy Red 2 is one solo dev (like Schedule I) making a WW2 campaign. It isn't anywhere near as polished as I thought it would be but it turns out it's still good. If you've played Enlisted you know the premise of commanding a whole squad with roles you can flip between. This isn't tightly designed like Enlisted, but the AI isn't AS stupid as Enlisted (it's still a little stupid). It's kind of like Enlisted with more jank to slow it down. You get long, sprawling historical campaigns from all kinds of theaters that will be introduced with no more fanfare than a canned Erika snippet and "The Germans counterattack" on some piece of shit hill that you know has been 100% accurately recreated but whose real world location or significance or any sort of narrative around what is happening won't be given to you.
It's the closest experience I've had in a veyr long time of playing classic COD, which is what I bought it for. So no real narrative beats - it's like playing Battlefield 1 operations - but for what it is, you have the same vibe of a WW2 game that takes itself seriously. I can't say as I've noticed mortars in it, which is gay. Artillery call-ins exist. Infantry roles are reasonably fun. Tanks are kind of interesting/fun. Unlike Enlisted my tanks don't die immediately, so you can actually have these duels where your tank gets treads knocked out, you shoot 50 times and never penetrate, you fight as combined arms. There's no reason to touch planes; they're included, but there's just nothing appealing about them at all when War Thunder exists.
Nebuchadnezzar is a Caesar/Pharaoh-like. I never played either of those, so for me it registers as Anno with obnoxious, autistic internal logistics instead of interisland trade. Central gimmick of it is this freeform monument construction but I haven't been deep enough into it yet to engage with it. I honestly don't find myself feeling creative; as a kid, I would have played for hours with that (like I did with Age of Empires scenario editors). Game is hard. Easy to go into death spirals, partially due to lack of quality of life mechanics like more granular control over warehouses. I just got to the part in the campaign where it mechanically unfolds with war mechanics. At first I was feeling peeved because I HAD fucked around in the tutorial of Tlatoani (which is free, but full game is for pay), and this is mechanically much simpler, but now I can't imagine dealing with Tlatoani's shit at the same time. Tlatoani's more thematically appealing to me and has gimmicks based around Aztec religious life (human sacrifices, the whole autistic calendar is represented, etc.). I'm sure it isn't included (stuff like this never is) but I'm hoping YHWH makes an appearance as a god in this game.
