I gave it a 10 because it's a very good game and I would still play it even with the games we have today Majora's mask is still a top game IMO.
I actually think the game play though very similar is better than
OoT. Even Epona was updated from
OoT to MM and I dont just mean a graphical change.
For example you can stear your horse while having the bow out. All you do is aim your bow as far as you can in order to stear Epona. You cant turn very well this way but it can be usefull.
Another thing I like about this game was when using ice arrows on keese or those black birds (cant remember the name) is when you shoot them they freeze and drop to the ground and shatter like a glass chanderlier, I found it pretty funny.
Even the equipment was upgraded from
OoT
2 examples are:
Gilded Sword. MM version to the Master Sword (in game play not story) It is better because it deals more damage than the master sword (I have tested this) and is still 1 handed. I also like the look of it more.
Swimming MM still has the best swimming method in any zelda game to date. Even
TP Zora tunic dont compare to swimming as an actuall Zora in MM.
