Unlocking the challenges that require a certain time in Brawl

[Lotos]

As in, multiplayer.  Does this mean that it only counts for the first player, or can I use four controllers and get four times the time I play that match for?  I'm not even at 10 hours yet :(  With the number of matches, it's one, no matter how many controllers are plugged in, right?

I'd like a screenshot or two to back it up, but it's not ABSOLUTELY necessary.  I just don't want to get jipped like when that Prima guide said I can play Solo mode for 20 hours to unlock Mewtwo.

I have a few challenges left to unlock (including, not limited to):

The 500, 1000, and 2000 KOs
Brawl for 30, 50, and 100 hours
Collect all Stickers/Music
All-Star Mode on Hard, Very Hard, Intense
Boss Mode on Intense
Beat 100 Man Brawl with all characters
Endure 15 Minute Brawl

Thanks in advance.  I will probably not respond to the thread, as I will be away until the 27th, so I'll bookmark this thread.

Nope. No matter how many players are in, you'll only get the amount of hours you actually played. As for the matches, yes, it only counts as one match each.

I only have collect all the stickers and 100 hours left.

just use two controllers, unlimited time (if it's still there) if not then do a really long match and then go have a snack while you wait :D
