I wouldn't claim they're quite so opaque, but Quakelike FPS games have a similar problem. They appear to be about shooting, but in fact at least 50% of the game is resource control (and even the combat itself is more nuanced than a new player realises). So when you're a new player losing to an experienced player, it can be super confusing and demoralising. Confusing because you probably don't realise why they are dominating you so hard and what you can do to stop it; demoralising because even if you persist and improve in one or two areas, it'll barely make a difference to the scoreboard. (You've improved your aim and learned to time items? Great, but the other guy knows the maps extremely well and can move around them far quicker than you, knows exactly how to position himself in a fight and when to use each weapon, dodges in unpredictable ways while predicting your own dodging and firing patterns, and so on. Meanwhile your newfound realisation that the armour and health items matter, and increasing ability to keep track of their timers, is making your routes through the map more predictable.)
I've definitely had similar feelings in Half Life 2: Deathmatch. I'm particularly fond of "low grav high kill" servers due to the fast pace (the low gravity enables a lot more movement around the map, and the "high kill" - i.e. weapons buffed / health nerfed such that getting hit by anything results in instant death or close to it - ups the stakes). Unfortunately, such servers often feature "sniper" maps, wherein players "in the know" will scramble to find the "hidey holes" and repeatedly slaughter any of us unfortunate schmucks.
It got to the point that on such servers I'd protest by refusing to use guns at all and used a crowbar and grenades exclusively. Not sure if anyone really took note of what I was protesting against, but it sure got me on top of some monthly crowbar kill leaderboards :)
Oh, tottaly! I was not trying to make a point that shooters do not have complexity at all. They do, even something as blut as CoD (I guess?). But especially for things Quakelikes or Team bases games like Rainbow 6 Siege theres a lot to be learned.
