Half-Life: Alyx
This has got to be the most narrowly targeted game ever.I played through all of HL/HL2/Ep1/Ep2 IIRC, but I can barely even remember the story clearly it was so long ago.  And it's such a blur maybe I never finished Ep2.I was 21 when HL1 came out but I didn't get to play it till I was like 24 maybe when I had gotten out of school and got a nice computer & some money.   HL2 came out when I was 27.. still playing games but I don't remember beating it till much later.  Probably 2010, by which point I was married and had bought a house.Now I'm 42 and I have a 7 year old.. so I'm old enough to actually remember this, don't really have the time to play anymore.. and I'd be looking at buying a new PC & VR equipment to play it.. yah no thanks.That and I remember HL2 and Ep1/Ep2 taking forever.  The whole thing was good, unlike time sinks like Oblivion and Skyrim that were full of filler, but it still took forever to play through.Just seems like a small target of players who are old enough to fondly remember the original + still have time to play long form games + still have gaming equipment + have VR/are willing to buy VR.Even as an engineer who knows more than a usual amount of gamers including younger players I'm not sure I know anyone who has VR equipment.
If you're 15-20 do you care about this or do you just think it's your Dad's stuff?
