DKC2 is the greatest platformer of all time. I have played the first world of tropical freeze and a bit of the second. I can't agree thus far. It seems to be pretty tight and right up there with all the rest of the series, but DCK2 has this foreboding atmosphere that puts it a cut above anything else really. Don't think it'll ever be surpassed.
Some nitpicks amidst what I think will end up a classic game -
Only Rambi (to my knowledge). Where's Snake? Parrot? Spider?
Only DK with supporting characters. But I want to play as Diddy as my primary, or Dixie?
Highlights -
Character design is utterly fantastic. Enemies look so cute in an attitudal kinda way
Music but that goes without saying.
Level design from what little I've played.
