The golden era of gaming was during the PS2. Not only did it have unprecedented market penetration, but the hardware was both advanced enough to make decent 3D games while not being so powerful that a few deep-pocketed studios could make stunning graphics that blew the completion out of the water.
Those days are long gone. On one end of the spectrum you have the indie market, which uses retro designs to make up for the lack of asset designers (think Rogue Legacy or Shovel Knight), or you have the massive AAA developers that dominate ad-spaces.
Anything in between (~PS2 graphics) isn’t taken seriously. So it’s either indie or AAA. No middle ground anymore.
The wii outsold the Xbox 360 and the PS3. The DS sold 160 million to the PSP’s 80 million, the 3DS another 75 million to the PS Vitas 10 million.
Games are designed to grab as much cash from kids and adults alike, with things like loot boxes, microtransactions, season passes. There is little focus on developing a community, and diminishing focus on shipping an actually good product. Today's games by Blizzard can not even hold a candle to names like Diablo 2, Warcraft 3 or even Starcraft.
