Ok before you even think about clicking that post button read the foillowing:
1). This is a topic where you post what ITEMS/GAMEPLAY ELEMENTS you would like to see in the next Zelda.
2). Do not post anything about what you think the next storyline will be, just the kind of gameplay.
3). Erm ...well.
4). Yeah that's it.
Ok this is what Zelda should've had in OOT and still probably can have.
OOT: Ok is it me or do you feel like after you saved the sages you feel like a pimp cheated out of his hos? No I didn't thought that would make sense, but what I am saying is the bloody sages seemed useless, they did two things. 1). Create that damn rainbow bridge. 2). Seal Ganondourf In The Realm. Now storyline wise that would've seemed like alot, but that was bullshit. You mean to tell me I got three stones and defeated 5 temples for the sages just to do that? Really that took the piss. "The Sage Adds His/Her power to yours" What? A bloody medallion? Thank you very much, maybe next you can give me a Wall-Mart voucher for my troubles. Anyways here's what they shoud've given you for each medallion.
Light Medallion: The abillity to move quick at the speed of light. The power up your sword with Light power making it more quicker and agile. To do various other moves with the light, maybe like super super spin attack.
Forest Medallion: I couldn't really think of much for this. Maybe the Forest Medallion could've upgraded all the deku weapons. The Deku Stick could extend, the deku shell could cover more ground. The sling shot could be bigger... I dunno. As for the sword power up maybe it could have the abillity to be a magnet to Hylian's plants (i.e. those little shrubs so you can get items like hearts/bombs/arrows attracted straight to you without having to cut it)
Water Medallion: Well the obvious thing would be to have infinite amount of time under water but the Zora Tunic is already there. Before MM's came out I would've said the power to to turn you into a Zora.. well that's pointless now. So maybe instead you could keep your Hylian body but be able to swim like a Zora. Oh yeah also you can be able to walk around in water as if you were on land without those damn iron boots. As for the sword power up it should be able let you use the master sword under water since you can't all.
Fire Medallion: Shoot out great balls of fire like with the Fierce Diety Mask in MM. The Power Up should make your sword on flames (that would kick ass) and maybe to make you roll into a great ball of fire, so you can have the same invunlerabillity like a Goron rolling. Also when you do a spin attack you also shoot out balls of fire in all directions.
Shadow Medallion: To be able to make different Dark Links of yourself so they can fight multiple eneimies. As for the sword upgrade it could've been the Dark Sword which could attract evil like poes, making it easy for you to catch them instead of using the bow and arrow. Also with the shadow power you could be able slide past enimies without getting hit (like Akuma in street fighter)
Spirit Medallion: This would so kick ass, since it is the last medallion it'd be cool to be able to posses enimies and actually use them as your tools. Basically you're possesing them like in WW when you posses those two allies of yours. There would be a spirit sword which could erm... hmmm....... I never really thought about that one. Maybe it would be an upgrade for the light sword.
That's all I could think of in ten minutes, hopefully you'll have more. Peace.
