ok, airing out some grievances on the indie scene. Pretty much anything billed as metroidvania/hardcore sidescroller/platformer/retro gameplay, whether it has retro pixel graphics or not. I am of the firm belief that the indie companies pumping out these games only played these types of games on super nintendo/sega genesis while really young and never had the "joy" of dropping copious amounts of quarters these systems were actually designed for. The difficulty wasn't a fun feature to enjoyed, it was a nickel and dime scheme for arcade machines. That's why when many of those games made it to consoles they had difficulty settings.
As to Free-to-Play, I can be a bit forgiving there because any studio outside of the Asian market desperately wants to avoid the pay to win stigma, so they allow ways to acquire things to pay for through grinding in game. Some are more grindy than others, sure, but if you want to lay down money, you're paying for convenience. Subscription games on the other hand, I'm tired of hearing all the same tired arguments about how they're so much better, how your subscription is paying for regular content, or how it's paying for better quality, how it keeps all the "kids" out of the game, etc. I've been playing MMO's/MUD's since the mid 90's, 3 content patches every 2 years isn't regular content when F2P games are regularly releasing new dungeons/raids/areas/expansions every 3-6 months depending on size because they're trying to get you to spend money. Quality is subjective and can mean anything from how well the graphics look while using a minimum of resources to whether the gameplay is harder than "don't stand in fire and score the highest DPS score". And I've never, not once, ever, seen subscription ever be a wall to stop children from playing a game. In fact I'd go so far as to say from my own personal experience that I've witnessed fewer underage players in the F2P games I've played, because they tend to not have the attention spans to stick to the grindy nature of those games, while adults tend to love that they can spend a little here and there since they have limited time to play.
