Silly Pudding
I've always wanted to try Dynasty Warriors, so when I heard there was basically going to be a Dynasty Warriors with Zelda characters I was so hyped and bought/pre-ordered it immediately. Been having a lot of fun with it now, but all missions so far are pretty much the same. So in order to not get bored with it I play in little sessions, since I'm afraid the fighting might get repetitive eventually
Dynasty Warrior games are really an acquired taste....
To reassure you, though, you can do two things to make things last longer:
Clear the game once. This opens up Hero Mode, which is harder than normal.
After that, set the difficulty to Hard.
Combine those two together, and you'll have to play a lot more cautiously and much smarter than usual, which should extend the replay value by quite a bit if the combat starts to wear thin for you.
Oh, btw?
Certain attack badges will extend the available moves each of your weapons have, and Nintendo is planning more storyline, character, and weapon DLC in the near future.[October 16, or somewhere near there, is when the first pack hits]
So, yeah, try out those suggestions, see if they work for ya, and have fun.^_^
