The Chieftain (Tank history and doctrine)
CGP Grey (Deep dives on random topics)

Lockpicking Lawyer (Lock history and picking)
LifesAGlitchTV (StarCraft 2 commentary duo)
Spookston (War Thunder gameplay)

Scott Manley (Space & rocketry related topics)

I haven’t used them in a while, but I used to go to Calgary Computer Wholesale

My city has a couple mom-and-pop type businesses doing it, I’d hazard a guess it’s similar elsewhere - never heard of any ‘big name’ outfits doing it on any real scale.

As far as I can tell, you are logged into both; if you vote or reply or save a post, it will do so on the account of the instance you’re browsing from. Now this can be confusing, because you can be looking at a post on lemmy.world through lemdo.id and upvote it on there, then if you browse through lemmy.world you can upvote the same post again with that account.

I personally try to avoid upvoting the same thing through multiple accounts (I have this one, but sometimes browse through beehaw) but it doesn’t seem like there’s any protections against doing so right now

Excited for this one - lots of great memories from the first Helldivers

Halo: Combat Evolved

I still find the odd person that never played it here and there, and yet everyone that tries it after says “Oh my god, how did I never play this game before?” and goes on to play the rest
