As almost everybody already said: Just try it. Get some protectors and a helmet - don’t give a single shit whether anybody would think that’s not cool or goofy or whatever. You love your body and want to protect it. That’s rad imo. Also: a helmet is more real estate for awesome stickers ;)

Then remember two things: bend your knees and lean forward. Also, you will fall and get up again. That’s part of skateboarding. Try to learn how to correctly fall: loosen your body and try to always divert the impact by rolling and “pushing the ground”. Find out if you’re regular or goofy and just go for it.

I highly recommend the beginner videos from braille Skateboarding on YouTube! They have a lot of tips for everything.

Look at that pure wrath in its little face!

EAC is fine, actually. They planned on moving to another Anti-Cheat that is definitely not supporting Linux (forgot the name), but this has been postponed atm

Strangely, I’m currently on the search for the exact same thing :D Your post was weirdly close to my own thoughts about this that I got stuck on it. Maybe you might try „Insurgency: Sandstorm“. Very very good Gunplay, some years old by now but at least in the EU or US it’s really not a problem to find a full match in about some seconds. There’s no grind - all weapons and attachements are unlocked right away, the only thing you can buy are weapon skins. It is on the „realistic“ end of the casual spectrum tho. Also, compared to COD or OW, the rounds feel rather slow.

Another one you can check out is „BattleBit Remastered“. It’s pretty hyped right now and kinda like what Battlefield should have been. It is extremely hectic and chaotic. The gunplay and customisation is really really good. Personally, it wasn’t really for me and I just could not get over the Roblox-Graphics… this one also works perfectly on Linux with Proton!

Honourable mention: with its Steam-Release it’s also a breeze to run OW2 on Linux! If you want to give it another try.

Edit: forgot this one. As you mentioned Halo - have you tried Halo: Infinite? This one is fucking infested with microtransaction tho… there is no chance to grind the content humanely possible without paying
