as someone who enjoys the fallout games i've gotta say it. i don't like the design of the t-51 power armor visually.
the eye lenses area looks weird, like why would you prioritize peripherals so heavily over seeing what's actually in front of your face. the shoulder pauldrons are really smooth and like, while i kinda get that, from a visual design perspective for making a thing in a game you'd expect a bit of greebling there at least. and so on
also on fallout stuff i think it'd have been cool if the intelligent deathclaws from fallout 2 hadn't been wiped out. and in new vegas and potential future west coast fallout games you could maybe run into their descendants sometimes in settlements or as part of caravans and trader entourages as guards etc.
maybe an intelligent deathclaw scholar npc in one town who has like. comical looking improvised glasses
definitely 100% prefer the sort of creature design we got in fallout 4 though, idk maybe if intelligent deathclaws were to show up again they could look similar but a bit smaller and with a more upright posture (though still hunched)
