Have you guy's played DKC2 lately? It's one of my favorites of all-time, and in regard to the "corner of time" nostalgia thing DKCR doesn't beat it. But in terms of controls (minus waggle) and pure level design/layers DKCR is the clear winner in 2011. The controls (hit boxes, timing, and feel included) in DKC2 are complete crap in comparison, and I say that lovingly. The level design in DKC2 is much more of a "theme park" type of design vs. Returns which is much more of a hardcore timing, rhythm, memorization. In that respect both are very different and at my current gaming tastes I learn towards Returns' style.
I agree though on the music, why Retro didn't include remixes of the best OST is beyond me. And they wasted Yamamoto's skills on remixes of DKC1 tracks and limited new tracks...lame. And I'll also agree on the enemy variety, which could and should have been better/more memorable. But the placement of the enemies, and their use within the level design destroys DKC2, imo.
So yeah, bring on DKCR2 Retro, and read this thread!
