OH YEAH!!!!!

I'd just like to put in my 2 cents here, and I know everyones first reaction is going to be saying I'm wrong, honestly, mine is too but with all the games I've played, ttrpgs, board games, card games, all sorts of different games with all sorts of different people, I've learnt this:

Any style of play is fine.

Now this doesn't mean in any context, but meta-gaming can be fun for everyone if you do it right. I've GMed a pathfinder game where I told all my players metagaming was fine because they all had a unique form of precognition shit.
Everyone took it their own way and stayed in character, but with metagamed knowledge. It was hilarious, the barbarian would run around bashing his head on things whenever he got OoC information because he thought his head was haunted.

I've played a game where the GM told us to min/max like fuck and start our characters at level 15, multiclassing optional. He gave us the most absolute piece of shit overpowered boss ever, and we needed every single number we could get.

I've played card games with some friends where we basically ignore the rules and it's just something to do while we talk, it's fine.

Any style of play is fine if you do it right, and doing it right means everyones fine with it, if this means for your group that everyone does it, thats what it means, but if you feel like trying it, go for it. If you all know what you're doing, it can be a lot of fun.

Meta-gaming without the fun is shitty.
Meta-gaming in and of itself is just a very picky playstyle. It only has a few good contexts

"IT, how may I help you? Have you tried turning it off and on again? You're welcome"

"IT, how may I help you? Have you tried turning it off and on again? The button in the front. You're welcome"

"IT, how may I help you? Have you tried turning it off and on again? Is it plugged in? You're welcome"

"IT, how may I help you? Have you tried turning it off and on again? What? That's just a monitor, sir, you'll need to come pick up the rest. You're welcome"

Better hope the sergeant didn't hear him or he's a dead man

i may be completely wrong but since hes in front of the unit colors he might outrank the sergeant. he definately outranks the SSG or SFC behind him

This is why i miss the stripes being on the arm. Made shit so much easier to identify

im guessing hes an MSG or higher. looks like red in his beret meaning hes enlisted. since its a big solid black blob id guess 1SG or SGM

lol, why so mad? Like I said, it's something I heard. I'm not an insider in the military. I'm just a civvie.

oh wow, didn't know it's like that

fucking awesome man!

this legitimately made me smile

you're also right, face to face is very important
