Pokémon Sword & Shield defines the 2010's more perfectly than anything else. Starts off promising, then turns out to be a load of garbage that makes you question how the fuck has this happened.
This decade was very polarizing. The good got better, but the bad got worse. Switch and Indie games exploded.
We finally had powerful consoles that weren't destined to be horribly outdated by the end of their 7 year lifespans. This was mostly thanks to the Pro and X versions of the HD twins. Single player games got better by a huge margin. Nintendo and Sony both returned to form with their exclusives (not counting Sw/Sh here.) The crafting genre exploded and was an awesome addition to gaming.
And then we have all the terrible shit from this decade. The rise of social/esports gaming. Some games like Overwatch, Apex Legends, and Destiny 2 deserve their popularity. Other games like League, Fortnite, and Poke'mon Go are trash, but hugely popular. The rise of lootboxes. MS taking a massive backseat in the console war, and not even trying to compete. The rise of EGS exclusives and the store wars in general. The fall of Bethesda with Fallout 76, and no Skyrim sequel after 8 years.
