How'd I forget Ratchet & Clank? I'd put that right after Valkyria Chronicles on my list.
And if you're wondering about Valkyria Chronicles, head on over to the official thread, where you can find plenty of details about the game, as well as player impressions, like these from The_vagabond7:
This game is absurdly awesome. Best RPG this gen hands down (any kind of RPG). Despite the HD revolution few games have awed me graphically but this one I just stare at in disbelief. I love being able to go into the character tab and just look at the character models, rotate them, shift them ect. I spent an hour just looking at character models in disbelief that they were polygon models and not just a 2d hand drawing, it's gorgeous.
The gameplay is unlike anything else, it is a truly unique strategy RPG. I've never played anything with a combat system like this game has. It's engaging, it's deep, it fixes alot of problems that other SRPGs have (level grinding new characters for instance) but without sacrificing depth or challenge.
It is a truly fantastic game. Sega screws up alot, but they can still make a world class RPG. I can already tell this is going to be a classic like Skies of Arcadia. MUST BUY.
