I'm also a couple hours in on the first R&C, and pleased with how this turned out.
The cut-scenes are presented in OAR - thank you devs! There's some minor clipping during in-game cinematics, especially around Ratchet's eyes, but this is very nit-picky. Sound is now in 7.1 and the audio positioning is great, but the up-sampling is somewhat harsh. Playing on a good sound system, much of the audio samples sound like low-res mp3 files. I had forgotten about the nice balance of difficulty (hover-board race!) because the modern R&C games are pretty easy. These PS2 games weren't hard, but deaths and restarting from checkpoints (!) happen enough to make them interesting. The first game also seems to be better looking the further I get into it. Every time I open a new planet and step of out the ship for the first time to survey the landscape, there's an "ooohh" moment, and I briefly forget I'm playing a remastered 11 year-old game! It's good these HD remasters are keeping character-based platform games alive.
Speaking of platform games, the Sly demo is amazingly short! It took me longer to figure out the X-jump O-grab/land mechanic than it did to run the entire route. But it runs so smooth, and looks exactly like the old Sly games with a fresh coat of paint, which is a good thing. And the cross-play with Vita keeps this on locked on my pre-order list.
