Yes I agree, but not all of it is hard to obtain, or at least, requires an obstinate amount of work and/or time. There's a lot of low hanging fruit, like say, if you're not going to have smooth animations, then at least having animations for each discernable action that the characters take. Jumping up and down, pulling levers, opening doors, etc. Rather than them just looking like they're standing still or walking the whole time. Even a solo guy can make say 2 frame animations for all these in like an hour or two. This is where it can start to look rushed, cheap or lazy, when even the low hanging fruit hasn't been picked.
You seem to think that cheapness, as in a small budget, equals laziness. That's what makes your argument such a hard sell. That is also what makes it come off as condescending towards your peers. Just because someone doesn't have enough time within their daily lives to devote 100% of that to making their game doesn't mean they are lazy. A game might take a single person six years as they toil away on it tirelessly in their free time. Time away from their day job, or daily routine. That person probably spent 20-30 hours a week, versus a dedicated team of even as little as three people working at a constant 40/hr a week pace. That's 120 man hours, vs 20 man hours, quite the difference the time makes. And that's a crude example, not even factoring in the insane hours people end up working on this stuff. My point is, time is literally money, especially if you are making a game with no funding, no backers, and no investors. To imply that everyone who wants to make a game can just drop infinite time freely to make their vision is preposterous. And to suggest that someone should spend a decade on muh frames at the risk of their own well being, and sanity is cruel. Some of the most inovative things come from limitations.
We can chop semantics all day about "smooth animations" versus "long animations" and make all our points, but it will come down to the individual. I don't care how many frames something has. It either looks, and feels, and sounds good, or it doesn't. Animation is only one facet of that. You seem to be referencing mostly obscure indie games with these claims of 'games making it to market with horrible animations'. What games, besides Undertale have such shoddy animations? I feel like making a thread about the animation quality of games on a fan game forum was a slippery slope. I think we all agree on some level that games should sound, look, and play well, but did Undertale really suffer as a game without those extra frames? Did it make the story less impactful? Did it undercut the sound track? Did it make game harder cause you couldn't tell what's going on? What games have you played where the gameplay has truly suffered cause of animations? There might be a handful of examples out there, but no one will remember those games in 10 years, cause they are irrelevant in the face of games that are good for multiple reasons, not animation alone.
Yeah, the market is saturated. And it will continue to be. As years go by, it becomes more accessible for people to get into making a game. Some people gain a following for a shitty game, an some great games probably go unseen by many forever. The music market is also saturated. That doesn't mean there isn't still good stuff out there, and to say that every artist should be >insert your epitome of musical composition, and why here< is insane. I like that there are thousands of styles, and types of games. If all games focused solely on animation alone, then other areas would suffer. I guess my point is, play what you like, and make what you like, but don't try to tell others that's the way they have, or need to do it. It comes off a certain way, and can be counter-intuitive to the collective creative process.
Either a game is good, or it isn't. It's a complex thing. Different people will get different first impressions in different ways. Different people will value certain things in games over others. I am not a professional game developer, and neither are you. We need to realize that. If animations are so important, show me your finished game, that is doing well financially that sells solely on animation alone. It doesn't exist. Cuphead is a bad example for me personally. I think it is a solid, albeit shallow sh'mup at best, that sells cause it has nice graphics. That's not a game I want to play. It's one example, but for me personally I really don't care about graphics here. If Cuphead used Atari 2600 graphics I still wouldn't care cause the core game doesn't appeal to me, and if it was on Atari 2600, it probably wouldn't appeal to you, either.
edit: I hope I don't sound like a dick, but this is an interesting subject.
