Half Life Alyx has set the scene on fire and every major headset is sold out, even the Index. It's not the only game too. Medal of Honor is coming, two walking dead games are coming out in the next 4 months in VR, Ubisoft is making a game and has made a full team to work on it, tomorrow a record breaking physics puzzle action game Boneworks comes out, the frontiers of VR are unrecognizable from when it started 4 years ago. Even from when I got into VR last year. It's not just about the novelty of being in the game.
The only genre it's missing is the classic PC genres, PDX essentials like civilization games, city builders, and grand strategy games.
I think there is a lot more potential than some people see. VR is maturing rapidly, games are shown off in development every month doing things we had thought were impossible or years off. Medal of Honor's next installment is VR and it comes out in March-April, it's a huge game with a staff of a hundred people putting multiple years of work into it. We've seen multiple RTSes come out this year, too. It's just a matter of time before Civ, City Building, and Grand Strategy enter the medium of VR. It could be a game where you play the president/premier/prime minister in first person, making phone calls, drawing orders on maps, and giving orders with your actual voice. It could be a huge globe in front of you and the kind of intuitive and tactile UI seen recently in Asgard's Wrath and Stormlands. Valve's basic physics and interaction system in The Lab lets me write as well in VR as I do in real life. New headsets like the index are comfortable and clear enough that I can spend hours in them reading, fighting, and working with no problems.
The only limitation is the imagination of those considering the prospect. It's possible and in time it will happen. I just hope VR grows as a market in the next year so Paradox gives it a chance.
