I have the 64 gig version and haven’t had an issue with space so far and have about 8 games on it, not exactly a lot to go off of but still got plenty of room left. I don’t have the standered headstrap on it but I think it had a decent amount of adjustment. Let me check some things and I’ll update with more accurate info
@Grex ok so I checked the original strap and ya it gets pretty small so I’d be very surprised if you couldn’t get a good adjustment for your kid. The game files range from a gig to 8.5 gigs (the walking dead was the biggest file and a pretty big game) so 64 should be plenty. Onward says it’s 9 gigs but I downloaded like 20 plus maps from the community workshop so those take a lot of that space up. I’m guessing the things he will be playing will be on the smaller size, 1 to 5 gigs at most probably. Any other questions?
