This is something I frequently do, picking games to go in blind with, it really can enhance the experience! Well I guess that depends on the type of game, for instance I went into Mario Kart 7 100% blind but that had nothing to do with my enjoyment, then went into Mario Kart 8 knowing everything and enjoyed it all the same. This must be cause those types of games have you doing the same things repeatedly over a short period of time. I can't even remember the first time I raced on Daisy Hills. But with adventure n rpg games, progress takes hours filled with story and events, so your first playthrough will have more of an impact. In Uncharted 3 for instance the falling out of the airplane part was so funny because I didn't know I was to grab onto the cargo so I just fell and died. Those laughs probably would not have been had without going in blind.
Unfortunately doing this is not without risk. Most recently I went blind into Sticker Star, thinking that one of my favorite series who's every installment I've loved couldn't possibly let me down, and that the confirmation of turn based battles was all I needed to know. Big mistake! That game is now my most hated! God if I had just looked at a single gameplay footage I woulda immediately known it was bad and saved myself $40. More related to this thread however is Skyward Sword, a game I went in 100% blind, and was similarly disappointed. Admittedly I was never big on Zelda, hence why I always go into their games blind because I don't care enough to follow them lel, though the few titles I played up to that point were pretty good, but then again I did find out right before purchasing that it required the Motion Plus, a pretty big red flag there.
Now although I do like going in games blind, it's hard for me to want to do that with Zelda U considering the bad taste it's latest installment left. At the same time, I'm not 100% blind this time, I already know one important aspect of the game, being that it's open world. My favorite Zelda game explored this concept and is definitely part of why I like it so much, so knowing that they're going back to it with Zelda U is a good sign. It also makes going in blind even more rewarding since exploration and sense of discovery will be big things here. This should also mean it wont have the same pacing problem as Skyward and it's overworlds also being dungeons on top of the usual dungeons. In general, there certainly wont be as much forced motion controls if any if other Wii U games are indication, but no guarantee of another Fi-like character lel.
Ugh wow I rambled a lot. Tl;dr, this decision is uber tough! I need time to think about it!
