That's me with like the entire GBA/Gamecube and DS generations of Nintendo hardware. I was playing EQ or PS2 from like 2002-2008 and pretty much missed out on everything else during that timeframe.
Yeah, I try to put together a "things I need to play" list every so often, probably once every two years or so, and get through like 10% of it before it falls by the wayside. At this point it's mostly the same retro things turning up on the list every time, since the 10% I get through are usually the newer things. That and the 300 hours I spent playing Elden Ring over the last 3 years really ate up like half of my console game time.
What I'm playing currently: Elden Ring Shadow of the Erdtree
What I'm playing next: Facing a dilemma here because I've got a ton of things I want to make a run at. Normally I'd make a list of things I "have" to go through, but I know the futility of that right now and am better off just picking one thing I really want to get into, and hitting it hard after I finish this DLC. At this point I accept that there are a lot of things I might never actually get to or play, I'll never "clear the backlog", and the best thing I can do is just choose something that interests me and focus on it. And of course making good choices because who knows how many more of these I've even got gas in the tank for.
Possibilities for next thing I get into:
-Elder Scrolls Morrowind (current frontrunner, and possibly followed by Oblivion)
-Breath of Fire 2 (my permanent "biggest missed SNES RPG")
-SaGa Frontier 2 Remastered (if I want to go really retro)
-Dragon Quest 8 (my only unplayed Dragon Quest, has been sitting on my shelf for over a decade)
-Xenoblade Chronicles 3 (XB2 was the last really big game I finished, and I liked it enough)
-Resuming the CRPG Crusade (probably Icewind Dale or Warcraft 3 next)
-Assassin's Creed IV and Rogue (been wanting to replay these for ages, midway through AC4 from earlier this year)
-Warhammer 40K Space Marine 2 (nice short one here)
-FF7 Rebirth platinum (super pumped for this)
-Dark Souls 3 replay (never got the plat, never beat Midir or Gael)
-The Nioh duology (pretty much always my "next thing I'm playing" frontrunner, never actually get back to it)
-The Nier duology (these are brand-new to me and I respect them too much to rush them, so probably not)
-The God of War duology (got the first one for free and it's been sitting on the Playstation ever since)
-Tomb Raider Remastered (never played any of these original PS1 TRs, always wanted to)
-Grand Theft Auto 4 (only modern GTA I never played/finished, friend has tasked me with playing through it before GTA6)
-Sell all my systems and go outside
Right now I'm definitely leaning Morrowind, though there are lots of strong contenders on here, and "go outside" is as formidable a contender as it has been in years.
