There are loads such games and it's a non issue, yes. I mean, your WIndlands 2 is already the 2nd. Only overly sensitive to motion sickness folks or those who haven't touched vr make such comments like it's still 2016 and people are worried about the now standard non teleport locomotion methods.
Grappling hooks, web swinging or whatever similar type thing is actually pretty damn tame locomotion compared to other methods like all the zero gravity, flying, jetpacking, hover skating, or whatever other VR games that are out there, or some that combine much or all of it pretty seamlessly.
There already are Attack on Titan fan game attempts so an official one makes sense too. Hopefully they get it right, the studio has only done small games before like their Little Witch Academia cutesy broom flying racer. Going for the "hunting action" (Monster Hunter) genre is a good indicator.
Anyway, this and other videos debuted in yesterday's
UploadVR showcase (the channel has individual videos), Idk why he didn't make one thread for it as most have 0 interest here and just clutter the forum, it's why I only post of VR in the Quest thread. He didn't even post the meatiest (Vertigo 2).
