Meh. 2010 wasn't that great either. I guess it gave us New Vegas which was good. But I can't recall any other great games from that year off the top of my head, meanwhile I can name a couple for years like 2004, 2001, 1999, 1998, 1993. 2010 doesn't come up with anything other than New Vegas though.
Meanwhile the indie scene is a lot more lively than it was 10 years ago. Back then we were happy when Jeff Vogel released a new game, or when an indie platformer turned out to be actually good. Now we have a dozen RPGs and strategy games of varying quality made by a single gopnik in his basement somewhere in Russia, and they're ten times more interesting than anything the mainstream can deliver.
Sure, AAA games have gotten worse and worse. Microtransactions, terrible DRM like Denuvo, mass market appeal, gacha lootbox mechanics, yada yada.
But the last decade has also brought us the Kickstarter indie revolution as well as easier access to self-publishing than ever before, with Steam opening the gates for literally anyone to release their games on the platform (leading to a deluge of crap but also hidden gems).
If we compare the latter half of the 2010s to the latter half of the 2000s, the 2010s win. Around 2005/2006 the decline had set in completely, most games were multiplatform console shit, long-running companies like Bethesda and Bioware turned into shit and massively streamlined what used to be great RPG series, shooters were dominated by popamole mechanics, everything was shit.
2015 however saw the release of Age of Decadence and from there it only kept inclining. ATOM, Underrail, Disco Elysium, Serpent in the Staglands, even Diablo Clone fans got their fix with Grim Dawn and Path of Exile.
We also saw a resurgence of classic FPS after almost a decade of popamoles. Dusk, Amid Evil, Ion Fury, Wrath, Hedon, Project Warlock. The boomer shooter is BACK, baby!
Strategy games are also looking quite fine. The recent Shadow Empire looks really interesting, the Age of Fear series is a series of tactical RPGs which keep getting new entries, we received a Fantasy General 2 that's actually pretty decent, Field of Glory 2 was pretty great, etc.
If you look past the mainstream AAA shit, things are much better than a decade ago.
