Are you genuinely having more fun now than with good games from 10years ago? Even 15years ago??

I mean yes? Certainly I can put another 1000+ hours into a game from 10 years ago or 15 years ago, but people aren't playing those games any longer, and those who do in a team setting are so far beyond anything a casual player can do it's not even close to being remotely fun. LAN parties were amazing, but they existed because most of us didn't have incredibly fast internet and we wanted to show off the PCs that we had cobbled together.

These days it's easy to fire up Discord or whatever chat you want to use, play a new game with your friends that looks great, that plays well (enough), and then you can buy a new game. I'd rather play Doom Dark Ages over the original Doom. Or to go to the 10-15 years ago metric, I would much rather play Doom Dark Ages over Doom 3. But hey, when Doom 3 came out, this exact same conversation was happening, because Doom 3 wasn't easy to run.
