Guess they're doing this because of the impending tariffs? It's certainly one way to avoid having to raise prices at least.
Technically MS already have the All-Access program but it's nice to see an equivalent for a console people actually want to play and isn't effectively dead in the commercial market.
All the more reason the next line of Xbox devices will 99% likely be PC-hybrids: gives them an excuse to iterate on new specs & form factors every 2 or so years and making that All-Access program useful.
That's...probably exactly why they're doing it this way? The ones who just want to play a couple of games for a little while but don't have a buddy or family to borrow a system from, can rent it. If they want a system, they can buy it later on.
If they want to have a system to own long-term but are fussed their rental payment won't redeem to the eventual purchase...welp, welcome to how rentals work in almost every other industry and have done so for decades

. They can choose to rent it out for a few months or save up their cash to buy the system at another date.
How is that a 'lol' when practically every other company on the planet that does a rental service for their direct products operates similarly? Or are people forgetting not every corporation has a $3 trillion market cap and a floundering games hardware division they can just subsidize costs on with a rent-to-own plan knowing only a small percent of their shrinking customer base would even be interested in said plan?
The costs of operating All-Access for a product as increasingly niche as Xbox is pocket change for Microsoft, especially after buying a publisher like ABK. They leveraged their massive size (from the non-gaming divisions) to enable things like that. No other company in gaming has that type of luxury, so if they offer rentals, it's likely purely to rent. If you want ownership, save up and buy or get a better job and buy down the line.
