That's actually really good way of describing how the fediverse works. We are all looking at the same conversation, but reading it from different servers that are providing us with their own graphical interface for that conversation.
The reason you see ask_lemmy posts when you visit kbin is because kbin users can also see lemmy posts. Similarly, you can see kbin posts. Anyone with a Mastodon account can post and reply to both kbin and lemmy threads, too.
but I dont know where or how to interact or if I am already by being on lemmy.
The thread you're posting in right now is coming from kbin, but you are replying to it from your lemmy account. So I think you're already doing the thing you described, maybe without even realizing it.
Glad to see all these recommendations -- I hadn't heard of Ground Branch, I'll have to check it out. This post is reminding me of how great the original Rainbow Six and Ghost Recon games where.
Also, there is a forgotten entry from the original developer! There was a video game tie-in for The Sum of All Fears movie, and it was basically a reskin of the original Ghost Recon with indoor maps. I remember playing the demo back when it first came out. Looks like it's on Steam, and the critics agree: it's meh! But I want to play it anyway now. https://store.steampowered.com/app/19810/The_Sum_of_All_Fears/
Side note: does anyone know a legit way to get Rainbow Six: Rogue Spear? I swear it was on Steam or GOG at one point, but I can't find it now. Thankfully, I have it on a CD from when it first came out, but I wish I could recommend it to other people.
