As far as future titles, I have to admit I wouldn't mind seeing some smaller (indie?) studios get a crack at DK, if just because we might get some quicker output in terms of actual releases.
I think the scope, graphical quality, and visual depths reached by both Returns and Tropical Freeze can be somewhat attributed to the budget that Retro had. However, there was a fundamentally sound gameplay core which made the games so fun to play in addition to being beautiful to look at; to the point where I think that aspect could be reasonably replicated/built on by a smaller developer.
Any such games likely wouldn't be the aesthetic masterpieces that the recent DK games have been (and I know to some degree that part has been a hallmark of Country releases), but a title like Impossible Lair demonstrated the potential of one type of evolution of DKC, And Playtonic managed to do so with both a lot of charm and without much of the resources that significant Ninteddo games have had.
If they give those indies enough budget to make it look as good and varied as the original DKCs at least. I don't think using The Impossible Lair is a good example of low budget.... because it's very noticeable in those game's assets. You always see the same circular chainsaws on every level (Sometimes they clash hard with the setting), the same city, factory, forest and sky city being re-used in multiple levels and it's very repetitive. The gameplay was enough to make up for the lack of variety, but I exited and tried to look out for different levels sometimes because you get burnt out of always seeing the same city.
About DK ports.... I'm not against them, but I think the best chance to have gotten a DKC Returns port on Switch would have been a pack with Tropical Freeze, it would have justified the $60 price and sold way more but noooo....
The obvious reason we are seeing so many ports for Switch is the fact that the console is portable, so it's the first chance we finally have to play many of these games on the go, that's why they are selling a lot, I have bought Okami, DMC3, Final Fantasies and such and it has been great.
But the pattern I have seen with Nintendo so far, is that if we don't see a port, the sequel is on the way, and if we get the port, the sequel was probably not being planned. I hope some franchise breaks that pattern soon, it's been way too long since we got any news and the drought is killing me
and the game coming out the 17th is so dissapointing I don't want to talk about it.
