I got the game last week, but I've only recently been able to play it. It's absolutely amazing, and, even though it's a smaller adventure, it's definitely a return to form for Ratchet and Clank. I also made the mistake of doing a Challenge+Legendary mode playthrough as soon as I could. The difficulty in this game is no joke.
Ratchet is also more of serious character this time around, but the humor of the series definitely isn't gone.
A few things:
-I'm still a little sad that Cronk and Zephyr have been killed off for real, though. I liked those two, and didn't see the point of them dying. No one developed because of it. It just…happened. I mean, Vendra and Neftin still had to be thrown in jail for war crimes among other things, but they made it seem like this is why.
-Also, I think Ratchet and Talwyn are an actual couple now. I don't really mind; vidya-game relationships fly way over my head, anyway.
-There are a few glitches here and there. The game-breakers have been patched, I think.
-Did I mention you see Cronk and Zephyr die? *KABOOM*
-If you're ever missing your Hover-boots, go back to Thram.
-Sound quality for a few cut-scenes is grainy.
-Ratchet can't swim. At all. You will die if you jump in there. Don't do it.
