Well, I've had the privlage to play both games. To say Skyword sword is pushing the Wii's hardware really isin't saying much (Especially for the Wii) and it hasen't thrown me with the motion control's half a second response time, as with any Wii game. As far as story, it's not as good as previous Zelda titles and not nearly as appealing... (Twilight Princess was far more engaging)
As for Skyrim, THAT really pushes the hardware of whatever it's on. WAY better than Skyword sword does, so if that's a point you're gunnin' for it's entirly wasted. As far as story, it's not the best in the world, but neither is Skyword sword. In fact, it has a level of complexity that deepens the more you play the game, in directions apart from the main story line. It's much more interesting, especially since this leads to the big obvious point that makes Skyrim better... (Don't even get me started on the gameplay)
Freedom. An Expansive world where you are free to do what you like, and will engage is some of the coolest quests and battles you'll play this year. Zelda is entirly linear and never deviates. Good game, but doesn't come close to Skyrim, or other Zelda games for that matter.
This whole thread to me sounds like a Zelda fan-boy wishing more people were talking bout Skyword sword because his parents won't buy him TWO expensive games. I recommend you grovel and hope for the best.
