Basically asking about great games that got ignored, consoles that didn't take off, gamers pre-ordering/paying DLCs or maybe even gamers paying too much attention to certain genres causing a saturation in the gaming market.

I'll start off by saying that I think it is a damn shame that Tearaway sold poorly (Vita and PS4) and I also find it a bummer that the Vita didn't sell as well as it should have.

Well, it's a shame online fees for multiplayer games ever became popular and successful. They are only here because you supported them, people.

the over-saturation of FPS games. in Gen 7 it felt like you either bought a PS3/Xbox360 to play FPS games, or a Wii to play anything else. and it hasnt brought any good to gaming. people are blaming it for mass shootings, violence, antisocial behavior, and disorderly conduct, and maybe a bit more variety wouldnt have let that happen.

also, remasters. let old games be and make something new. the only company who gets a pass is Nintendo. the Pokemon games have a designated schedule for remakes and the Zelda remakes were all just at the right time

Not enough people play illusion games

Buying handhelds even though there are smartphones now.

They support too many military shooting games.
It has left us with far to many of them for my likeing.

I kinda miss the SNES/PS1/PS2 days, far less shooters back then, and more of everything else.

The demise of 3D platformers and arcade racers, cause we have to play grown up games with gritty gun play or realistic sims with steering wheels.

Paying into micro transactions, sustaining free to play, basically allowing games to become a grind unless you pay and removing the tradition of cheat codes and free unlockables.

I did buy Tearaway on ps4, never finished it though. It's very pretty but kinda boring to play :( I had the same thing with Puppeteer, well made but too much blah blah.

People played mostly FPS on PS3 and 360 and "anything else" on Wii?

Sure, all those first person shooters on PS3/360 like Gran Turismo, FIFA, Madden, NBA, Uncharted, Ratchet & Clank, Assassin's Creed, LittleBigPlanet, The Last of Us, LittleBigPlanet, The Walking Dead, Batman Arkham series, Final Fantasy series, Street Fighter, The Elder Scrolls / Fallout, Heavy Rain, inFamous, Journey, Flower, Need for Speed, MotorStorm, Lego games, The Sims, Guitar Hero, Rock Band, Portal, Minecraft, Fable, Forza, Kung Fu Panda, Dead or Alive, L.A Noire, Skate, Kinect Sports, Life is Strange and hundred of other games... all the same genre...

And of course Nintendo gets a pass for their remasters while every one else should let their old games dieand aren't allowed to offer an improved version of their games.

Smash Tennis (SNES) Is one of the best Tennis games of all time, but no one has ever heard of it! An outrage.

I wanna add

-buying microtransactions in a $60 AAA game

-Not wanting to support indie devs because their games don't "look" AAA

-discussing games over the internet more than playing them. (ironic I know)
