I've had my eye on RGO for a while now (just waiting for it to come out on Switch). Does look very good, as the article said, a bit of a Firefly feel to it (also reminds me of a small-print tabletop RPG from about a decade ago called Star Thugs).
Much better than the pyramid scheme that is Star Shitizen. I also didn't realise the new Elite was so sparsely populated. I thought part of the reason for forcing it to be always-online was that players would interact (although partly it's apparently the size of the client required to run the universe in the background). The always online bit was enough to put me off though.
Other awesome space sims are the X series (X3 with plety of mods is incredible but you really do need to devote a lot of time to getting good at it and building up your little space fleet).
Colony Wars on the original Playstation was very good, proper Newtonian flight physics and some cool battles. The original X-Wing is really the daddy of them all, such an amazing game. I loved having the ability to divert power between engines, weapons and shields, depending on the situation (I fondly remembering retreating from missions in a damaged ship, shoving all the power to the engines and focusing deflector shields to the rear).
Eve isn't a flight sim, in the same way that World of Warcraft isn't an action combat game. You click to attack then watch your ship orbit the enemy and occasionally you get to activate a special attack.
Everspace looks good, although I've heard it's a bit dull after a while (which is always a risk with procedurally generated content).
Subdivision Infinity DX has just come out on Switch and looks quite good, also has the stupidest name for a space sim ever. Sounds like some sort of dance game.
Starlink was almost an amazing game. Really fun to play but the toys-to-life bullshit killed it completely. Not much in-game progression because that was all locked behind a paywall. Buy the toys to unlock new ships, weapons and pilots. It's annoying because the game is well made and loads of fun. I bought the starter pack on Switch in the bargain bin for £20 (launch price was £60), got myself a cool Arwing model, and then bought some other ships from the bargain bin. Even having got it very cheap, the game just didn't work as well as it would have done if it followed the usual format of letting you unlock ships and weapons as you go along.
Oh, and for the author of the article, the Double Damage FAQ suggests you can turn off all the aim-assist nonsense, if you feel like taking the stabilisers wheels off and flying like a grown-up. ;)
