I was a bit meh on Star Rail at the beginning but I'm absolutely loving it now.Well that is a shame and thanks for the heads up. I may just go back and play Genshin instead. Or Honkai Impact. Or FGO (Especially as I don't have to jump through hoops to play it in Europe now). I'll play a bit longer and see where it goes. But now that I think about it, the game does seem a bit less "complex" than Genshin was at launch.
It really is a shame as the story seems interesting and, as I said earlier, Honkai Impact has a great combat system as well.
I was a bit worried about combat at the beginning as well, but it seems fine now honestly. A lot of the depth is still in the teambuilding part of things - which characters to use that have synergies between each other and can make use of the enemy weaknesses, but enemies and bosses also start doing some interesting things to shake things up so I'm sure they manage to come up with even more stuff down the line and once you unlock World 2 of the Simulated Universe (the roguelike mode) there's a lot of fun buff synergies you can set up.
It's never overly complex in combat itself with a lot of the strategizing outside out of it, but after playing a lot these couple days I'm actually fine with that and think its a smart decision. Think about it - they want you to be playing this ideally every day. If every encounter is a 20 minute ordeal that requires your full attention, I'd probably start finding it a chore very soon. I think they struck an alright balance for now - will have to see how I feel about it in a couple/weeks months.
The real winner for me here is the writing though. Main story is standard JRPG stuff so far (I'm at the end of the first planet). Nothing really special, but well executed and well paced, with some hype moments.
The side stuff however is fantastic. The side-stories kinda feel like Yakuza - lots of extremely silly stuff that effortlessly transitions into something emotional/thoughtful/sad if they want to. And then the maps are filled to the brim with interactables that have tons of hilarious flavor text.
Regarding the gacha stuff/pay-walls etc: Hoyoverse games imo are extremely free-to-play friendly. They give you everything you need to complete the game for free. The free characters in Star Rail are extremely good. Genshin gives you everything you need to do all of the puzzles, explorations and story as well for free. The story mode in Honkai Impact doesn't even use your gacha characters.
They will however not give you everything for free. You'll get a decent amount of "paid" characters if you play the game regularly, but if you are a collector that wants absolutely every character, things are gonna get expensive... But again, there's no need for that to complete all of the content in the game. Star Rail could go a different way, but from what I've seen so far I don't think that's likely.
I read someone saying their games are effectly "Pay to Simp", lol, and I think I agree. They want you to get invested in the story and characters via many different avenues (design, animations, voice acting, personality, backstory, etc) so that you'll want them and want so spend money for that, but they're not gonna lock you out of any content if you don't do that.
