This is an excellent addition to my game collection.
It is one of the best adventure games out there,
and plays well on my Xbox One X console. I suspect
this will become a collector's item in ten years!
It is on sale at an unbelievable price, and will probably
go out of stock in the near future.

Excellent set of budget headphones. I use them with my
"new" Galaxy S22 phone. They provide good stereo sound, that is considerably better than that from the
speakers of the phone. They drain the battery of the
phone far less than the phone speakers, or than using
bluetooth headphones. They deliver very good value.
