Good for business not so much for the purchaser if the company goes sour. Still probably will get signed up soon as my son upgrades to a meta 3 and sells me his 2.I've played with some VR FPS stuff (not that one specifically) and it definitely adds to the skills in a way that's hard to do otherwise (breaking 180, multiple threats, moving threats, stuff appearing and disappearing). It's no substitute for dry or live fire but it's another tool in the bag, it's definitely better than nothing.
Product as a service (subscriptions) is a pet peeve of mine but a good business model. Sure it's substitution (spending money on X instead of Y isn't saving) but the 20 bucks a month will get you what, not even 2 boxes of ammo.
