There's a reason we don't see any big Let's Players do more than a couple episodes of VR games.
That doesn't mean they're not having fun, but it's quite physically demanding and the experience just doesn't translate to 2D.
I love Half life alyx. I played maybe half an hour, and i don't think i'll ever play more. Just the thought of putting the vr headset back on puts me off. I thought VR would be great for me, because i do a lot of sports anyway and i like to move around. But sweating while playing video games isn't as fun as it seems. Especially when you sweat a lot in and around the goggles. Like i said, it's an experience, not really more. On a side note, i also learned i'm a huuuge pussy when it comes to VR games. I really don't know what it is, i was never scared of a movie or video game or anything really. In vr looking into a dark hole where something might jump scare me, really isn't for me at all.
Fortunately I don't sweat that easily, Alyx was fine for me so far (about 2 hours in). What REALLY gets me going is (modded) Beatsaber. I can only play it wearing briefs and it's a serious workout if you want to challenge yourself, but it's so much fun that I've managed a few play sessions that lasted for over 3 hours.
