The Xbox One has had a great deal of criticism this week, but it appears there is at least one person on the side of Microsoft - Gears of War co-creator Cliff Bleszinski.
Bleszinski's argument is that with the cost of making triple-A titles getting increasingly more expensive, publishers simply can't recoup their investment while the used game market exists.
"You cannot have game and marketing budgets this high while also having used and rental games existing. The numbers do NOT work people," he Tweeted.
He continued: "The visual fidelity and feature sets we expect from games now come with sky high costs. Assassin's Creed games are made by thousands of devs."
"Those of you telling me 'then just lower game budgets' do understand how silly you sound, right?"
And the former Epic man also suggests gamers angry at the Xbox One 24-hour online check-in should direct this frustration at internet service providers, not Microsoft.
"If you can afford high speed internet and you can't get it where you live direct your rage at who is responsible for pipe blocking you," he Tweeted.
Bleszinski also believes any talk of Sony's PS4 having already won the next generation battle is premature.
"If you're saying the next round of the console war is over before it even started then you're a f*****g idiot. This is a multi year fight."
Just in case anyone thinks Bleszinski is biased towards Xbox, he's "buying both a Ps4 and an Xbox One".
Xbox One launches this November priced £429, with the PS4 also out this holiday at the lower price of £349.
