Sekiro: Shadows Die Twice was life-changing for me. There’s quite a bit of exploration that will let you experience various bits of deeper lore, including an entire hidden story that links up with the backstory of one of the minibosses. Not sure if that’s what you’re looking for, but I really enjoyed this one.
This video goes over it fairly well (note that this video does contain minor spoilers): https://youtu.be/O-x-1kS6TpQ Another video that goes over only the gameplay with no spoilers: https://www.youtube.com/watch?v=oBv8UVOSG8U
Spoiler-free TL;DW: Halo 4 was controversial because this was the first new mainline Halo game by 343 Industries, who changed things up from previous Halo titles.
But aside from questionable changes to the franchise in order to appeal to the CoD audience, there were a few genuine issues with the campaign (in my opinion, as a player who never finished Halo 4’s campaign).
In terms of gameplay:
The result is that you are basically limited to only using long-range weapons to take out enemies. Hope you enjoy hours of Light Rifle gameplay!
In terms of other parts of the game, this is more subjective but:
Overall just a poor experience compared to older Halo titles.
I think that if you’re looking for a Linux distribution that is as polished as the Steam Deck, then SteamOS on desktop might not be the right play. SteamOS will probably (rightfully) be developed solely for handheld, low-power devices, and won’t work unless you’re using the specific APUs that they’ll include drivers for.
If that sort of streamlined experience interests you, Bazzite has very similar goals to SteamOS (good OOTB gaming experience, safe updates etc.), except that they also target wide hardware compatibility. Other gaming distros exist, but I’m probably just not aware of them.
