Alright so... played it for some 15 minutes after waiting almost 20 minutes for all the WiiU updates and all that shit and.... I'm lovin' it.
I'm playing with the gamepad and for now it's taking a bit of time to get used to throwing pikmin with the analog stick, but I guess after getting used it shouldn't be so bad.
I have yet to get any big amount of pikmin, I'm right now at about 30 red pikmin so it's not so much... but the game has a few really neat details like the topview map (you can pan around the whole map on your gamepad and the 3D view shows on the TV), and it also has a camera (I didn't know about this because I tried to stay away from anything related to the game) so I can expect great pics to start showing up soon.
For now, I took a few pics (2 with the camera) so here they are:
Red Pikmin doing their best trying to build the bridge.
Pikmin looking at me instead of working! (taken from the gamepad screen directly)
The top-view while in the map (TV screen).
Red pikmin moving a 5 piece (taken from the camera, it uploads the image to Miiverse directly and lets you add a comment, you don't need to go to Miiverse pressing Home).
And yeah, in movement it feels and looks better than in screens. My only issue right now is the controls, but they are not so bad it breaks the game, so I guess I'll get used to it.
