Did this for Nintendo a few weeks back, ( https://gamrconnect.vgchartz.com/thread/250479/2000s-nintendo-vs-2010s-nintendo/1/ ) but thought it could also be asked about gaming as a whole: which decade of gaming do you think was better, the 2000s or the 2010s, and why?

I would say the 2000s. The 2010s had the Switch which I really loved, but the early 7th gen years were just so amazing. My favorite time in gaming ever. Also the most successful gaming generation of all time! Every console felt so distinct: You had the DS with its dual screens and touch screen which produced one of a kind experiences. The Wii with its motion controls. The Xbox 360 which was just an amazing piece of hardware and had a totally different vibe. And the PSP, which was the first handheld that brought console gaming to our fingertips (and the game were so cheap! The PSP Essentials were 7.99€/$ each for a full-fledged game!). The only console that was a bit disappointing for me was the PS3 but it too had many great games.

Also, the 6th generation was the last time we had this absolutely huge jump over a previous gen. Games didn't just look totally different, they also felt completely different. And many 6th gen games still hold up and feel quite modern today.

SSX3 was 2003 so 2000s

The 2000s had the bigger high points but the 2010s probably had better average quality.
