All the role-playing games are:
-JRPGs (with a combat system that's mechanically behind their Western counterparts of the late 80's), or
-Roguelike/permadeath, with almost no real content and everything's randomized (or even worse, a Skinner box where the entire purpose of the game is to level to get better gear), or
-"hardcoe"/"difficult"/"unforgiving", or
-Dungeons and Dragons style (turn based, grid movement, tabletop mechanics), or
-card games/board games
All of the scrolling combat games ("shmups") are:
-Japanese "bullet hell"/dodge everything or die, or
-Mid to late 80's retro throwbacks with grossly simplistic mechanics. I've seen several space invaders clones already with absolutely no innovation, just reskins of the same, or
-Infinite survival (because the industry is currently obsessed with roguelikes and random everything), or
-"hardcoe"/"difficult"/"unforgiving"
All the platformers are:
-Mario clones, or
-Sonic clones, or
-mid to late 80's throwbacks (mechanically simple, no health bar)
-"hardcoe"/"difficult"/"unforgiving"
-"Metroidvanias" (perhaps the only Japanese video gaming paradigm that I actually enjoy, unfortunately so many indie devs figure out all sorts of creative ways to screw them up)
There's also a large glut of "point and click adventure", visual novels, and similar which arguably aren't even real games.
More and more shovelware as well, there's also a glut of "abstract"/"minimalist" games (just a nice way of saying minimal effort, minimal game mechanics, and the entire game makes no sense). Similar to "abstract art" which anyone can make with a canvas and a paintball marker loaded with randomly-colored paintballs.
Then there are the idiotic real-life simulators (walking simulator, parking simulator, mechanic simulator, farming simulator, ...) that appear to be little more than someone goofing off with Unity and looking to make a quick buck off the resulting product.
I'm also seeing a repeating problem of lack of content. All too often, games will have so few levels/areas that it turns into a waste of the game engine. I've seen a scrolling shmup with only 6 levels at the bottom of the hall of shame. Why do people think it's acceptable to release something with so little content?
Indie games are also turning into a contest to see who can be the most "hardcoe/unforgiving". It's getting annoying and old already, only serving to lock most players out of content. Perhaps this will be the year where I'm going to be just as "unforgiving" to the industry and refuse to buy anything new until they stop being elitist jerks.

Looks like I've been proved right... that out of the droves of indie games, almost all that's been produced has been false choice, where most developers do the same thing with little innovation.
Also: I enjoy classic games from the mid to late 90's... almost anything before that is usually too old and simplistic to be any good.
