I find it annoying when reviews encourage pity-buying a game just because it's an indie game made by one person. While I could appreciate the hard work such a game would require, if the game doesn't appeal to me (whether it's because it's an indie game lacking the budget of a AAA game is irrelevant), then it doesn't appeal to me, and I shouldn't be guilted into spending my hard-earned money on something just because some other folks want to squander their money on supporting indie developers. Would you pay a large sum of money for a low budget mobile game over a AAA game just to support the developers? If you want to do that sort of thing and support the indie industry, it's your prerogative and more power to you, but don't gaslight, manipulate or guilt-trip me into buying it, saying how "other reviews are comparing this game to a AAA game." Of course they make comparisons to AAA games - they have a bigger budget and are a lot more fun, and therefore they feel those AAA games are more worthy of purchase. That's the sad reality of the industry, and no amount of good intentions from indie developers is going to change how cool-looking and high quality gameplay a AAA game will have over most indie games. If your positive review of an indie game requires the dismissal of the "high budget" of AAA games to make that indie game look better, then maybe the indie game you're defending just isn't that quality to stand on its own merits without comparing "developer budgets."
I like Undertale and Spiritfarer, for example, but as much as I love them, I'm not going to pretend that they're far superior games than most of the higher budget AAA games I've played in terms of gameplay mechanics, game length, storyline and especially visuals. The specific game that got me to talk about this issue, however, is Prehistoric Kingdom. It's been in development for over a decade now, and many reviews complained that it has the bare minimum a dinosaur park management game should have, and I think that, at the very least, they're justified in feeling bored, even if such criticisms might've been unfair towards the indie developer working with a minimum budget. The sad reality is that if you're working with a lower budget, your game will have less features than a higher budget game like Jurassic World: Evolution 2. For all the flaws of JWE2, it's undeniable that it has 1) a lot more dinosaurs, 2) higher quality visuals, 3) a lot more gameplay features. That's not a subjective opinion; that's a fact. It's an opinion to say you enjoy the minimalism of Prehistoric Kingdom, but it's disingenuous to say that Prehistoric Kingdom should be bought just to support low budget indie games, especially when they haven't done jack to develop the game at all for 10 years. It's like begging for a charity case, and it's manipulative.
