Yeah I'm loving it. Powering through Legend Mode a few hours a night (Friday, Saturday, Monday so far -- I had to work a double Sunday so no love there) and I'm just 1 stage into Ganon's story.
Then today my buddy came over for 2p madness - the no split screen thing by using the gamepad is pretty nice (aside: Yeah I have no idea why Gamerforlife's system tried to make him use a Wiimote, I've never used a Wiimote with my WiiU. I just use the gamepad for everything because as mentioned before it lets you track the important people at a glance). And having him there means we were able to get a bunch of Skulltulas (7 out of the 8 stages we tried -- I just couldn't find it in the stage with the boulders, but we had gotten the heart containers so called it a win and moved on rather than replaying) and/or heart containers.
I feel as though I've barely scratched the surface here. I'm buying as many badges as I can, but clearly there's a ton (and I feel like the Gold materials are only going to drop in Hard mode) to buy. I've barely touched the Armory, I haven't brewed any of the potion-thingies (I forget what they're called) at all. I haven't touched Adventure mode.
Gonna sink a looooooooot of hours into this. Which is good, because then I feel like the fact that I bought a system for 1 game is less bad

But then, I've loved Dynasty Warriors since playing #2 (which was the first one in the current incarnation really, the original Dynasty Warriors was much more of a straight-up fighting game) a good... 12 years ago or so? Whenever it was current. And I've loved LoZ since the original. So it was kinda no brainer for me.
