Instead of the crisp 2064 x 2208 pixels per eye dual-display setup of the Quest 3 you have to make do with the Quest 2’s 1832 x 1920 per eye single display setup, which the Quest 3S is repurposing.
When the older Quest 3 launched last year, it came with Asura'a Wrath 2 for free for a while, and that game still costs $60 if bought separately, so don't sleep on this on these Meta Quest 3S bundles.
