Sorry for the 3rd post in a row, but this one is firmly on topic!
I just actually played the DLC, not quite sure what to make of it. Let's go step by step (I haven't tested out local co-op)
Main game - They've improved some menu and HUD stuff which is nice. They've also added a statistics page which says 0 for everything. I remember this happening in Super Stardust a lot, there's no point in it if it just keep sending you back to 0. Uncharted 2 has a similar issue where it's not clear whether the stats are for one gameplay, or all of them, or a couple
I only played a level on rookie and it's clearly much easier than before, borderline boring. Rookie used to get my heart racing a bit, but as I warm up again, I'll move back to the proper difficulty settings
Ship editor - I downloaded the X-Wing and Gummi ship immediately and they look nice, but I found making a ship a bit of a pain. I'm not sure why, but it just seems so fiddly. Speaking of the gummi ship, the KH I (HD remix, but I think it's the same) editor was much better, certainly in terms of moving in 3 dimensions with the d-pad (use shoulder buttons for height) and I felt the camera was lacking.
But the only issues with the end result were in artistic design, that's my bad
Survivor - Should be fun, probably need some more time to adjust
Demolition - Dunno. I'll give it some more time, but I'm never convinced about their modes where they stray too far from the core gameplay
Overall, the actual DLC isn't that great, but it's a good excuse to get back to a great game. It's also dirt cheap so can be forgiven
