Today I booted up Skyrim after spending last year playing BotW, and Horizon. There were just too many things that I noticed that just felt dated gameplaywise.
Stealth has little to do with whether or not you are in an NPC's line of sight. You can be standing right in front of an NPC and if your stealth is high enough you are hidden. There's no way to move out of line of sight quickly either. Horizon and Zelda both provided a lot of movement options such as walking tightropes, climbing trees, etc., that just made stealth feel more dynamic. Both games provide high grass to hide in ala MHW.
The PC in Skyrim holds it's hands at eyeball level, which is weird looking. Who holds their hands like a T-Rex in heat? Not to mention it blocks the screen. Third person view is preferable, but the camera just can't handle that correctly.
Combat is just casting spells or swinging your weapon. BotW and Horizon both let you do really neat things with their combat system. One good example is the time slow during falling with a bow. Combat in the two latter games just feels smoother, and gives you more options.
I've felt this way about the game at launch. I honestly have very little understanding at why a great many people hold this series in such high regard. The worst thing about this game though is the dialogue. It's like 500 pages of dialogue with mediocre delivery, and inane statements. IMO the legend of zelda 2 for the nes does a better job with dialogue that this, because at least you know that everything you hear aside from "i am error", is some kind of hint or guidance. Hell, you want a game with a shitload of dialogue along with meaningfulness? Check out neverwinter nights 2. Skyrim is actual monkeys-at-a-typewriter, and it ain't no shakespeare.
