I really want to see remakes of the original trilogy that stays faithful to the original games in gameplay and tone but expands on things nonetheless. In particular, this being the Dixie thread and all, I feel like DKC3 could have a lot of potential being remade.
I think one thing that makes it sometimes compare "unfavorably" to DKC2 is the fact that the developers did not go as hard on the theme on the game as they did in DKC2. Traveling from world to world felt "random". The enemy designs were also weird but not weird enough or consistently weird enough. The "story" doesn't need to be deep or with a lot of cutscenes but I still felt like they could have done a better job at communicating that Dixie was searching for DK and Diddy. Perhaps like items that relate to DK and Diddy at the different bosses. Like Dixie is checking first in Lake Orangutang (world 1), and defeating Belcha ends up with Dixie finding DK's tie. Defeating Arich leaves Diddy's cap, etc. Dixie's checking every corner of the Northern Kremisphere in search of her friends. Maybe the Bears could point her this way or that.
Also, regarding the villains. Imagine seeing a DKC3 remake where Baron K. Roolenstein being a scientist played more of a role in the game. Like in the later levels/worlds, Kremlings become gradually more mutated/mechanic etc, gaining new abilities. I feel like the entire last world of DKC3 should also be remade and play up the mad scientist or horror theme. Like imagine a village level but full of Kremling Zombies. The village could be full of Bears since that's a DKC3 thing I guess. Put K. Rool's castle on a cliff. Play up the Frankenstein and horror motifs. Have K. Rool experimenting on one of the animal buddies that doesn't show up in the game normally like Rambi. Make the Baron K Roolenstein boss more physical. I want to see Dixie grab K. Rool with her hair and slam him on the ground like she does Kiddy.
Speaking of which, I also would really like to see Dixie gain new abilities. Like since she's the star, extend her hair powers so she can do new things and play in a new way that DK and Diddy can't. And Kiddy...I say keep Kiddy. But maybe change him up somehow. Not sure, but I remember reading on this thread someone suggesting an even smaller Kiddy, like an actual baby, that could be interesting.
Just rambling thoughts. Nintendo ninjas you can take whatever idea you want.
