I don't think this game will be boring if its considered to be a repetition of the old games, 15 years is a long time, I'm sure the new generation of gamers have not really experienced all three games so it wouldn't be bothered by that, and the old gamers that still play don't want to see the game drifting away from the original roots.
I made it clear I was really disappointed by Retro choosing not to include at least part of the original batch of enemies from the series, and now they drop another bomb, no water levels?
wait , what? why ? There is enough technology to make a water level fun in case they think it was slow and boring as they said, plus I don't agree with their opinion, the games were filled with fast paced levels, those water levels offered a good balance to the game.
Now , I don't know if its clear but no animal buddies?
From the trailers I have only seen very weak and poor designed enemies just sitting there not doing anything in a very very slow paced level, so there might no use for animal buddies at all.
For sure I won't be one of those that will automatically love the game because it says Donkey Kong in the title, I'll wait and see, even though for now the game really looks awesome and I'm sure it will be fun to play, those few bad choices really hurt the game from being a true successor to the series, in my opinion. I get the feeling I will be playing and saying " what if they did this instead " through the whole game.
