I would be okay with the next Zelda game adopting a similar fabric/material art style to the Zelda themed game in this.
I don't like this art style that much but I wouldn't mind them going for it just to see something new and a bit different.
Nintendoland Pikmin is pretty fun.
It's a bit of a sampler of Pikmin 3.
Everytime I start this minigame, I remember Pikmin which was my first game on the gamecube. I remember playing it without a memory card so I had to start again from the beginning everytime I turned the console off. After a few days I got good enough at it to finish the game in one go. Needless to say, nostalgia tears everytime, I cannot wait for Pikmin 3 and hope I won't be disappointed.
I picked this up but really haven't played it much (one game of the Ninja game). Been giving all the time to NSMBU and ZombiU.
The question is: Does this have decent replay value if you aren't doing multiplayer?
Basically deciding whether to put more time into it or just sell it while the credit price would be decent.
Games have a surprising amount of depth for the most part. When people hear mini game collection, they usually think mario party mini game style, fun but shallow. This is not really the case for Nintendo Land. Single player games are decently long, and have good replay value if you are into speedrunning and getting better scores. Sadly, this last aspect hasn't been explored enough (absence of online leaderboards). The three cooperative/solo games seem to be pretty long too, I haven't finished them yet.
You'll probably need to play some of the solo mini games and see if you're interested. They may appear simple on the surface, but they're hard to master. Should try DK crash course. They also are a pretty good showcase of what Nintendo aims for with the wii u, so playing them gives you an idea of what to expect. My advice is playing this game with another person (gf, wife, roommate, friend) even if it's only single player with one watching on the TV, it's way better this way.
I guess it's cool to keep around for the multi too in case you have the setup/people for it one day.
