I used all my hammers before and I regret it. I only need to complete 4 more challenges. Boss Battles Intense, 100-Man Brawl w/ everyone, collect all stickers, and collect all CDs. I've almost completed Boss Battles on Intense one time with Charizard but man it was hard.
Melee had what? Less than 300 trophies? That wasn't too hard. Brawl wants me to get OVER 500? How many are there anyway? I don't even want to think about stickers...
Melee had 290 trophies. Brawl has over 500 trophies I'm pretty sure. There's a lot to get in the game which is nice because I love collecting a lot of stuff in games, like Majora's Mask. I think there are 700 stickers in Brawl.
I had this idea of doing the subspace again because maybe the boxes containing CD's will be available again if you play through a second time. If you were to play through a level again where you got a CD, the box won't appear again. I'll probably try the item thing to test my luck.
