Well! At least you can train a lot with the same chars in the All Star mode.
I miss Board The Platform too. And... I'm wrong or Run To The Finish doesn't exist anymore?
You are correct, sir. Race to the Finish has been eliminated.
I, personally, am not happy with the sequence. At first, I enjoyed Adventure the most in Melee (as most everybody probably did). But after I got sick of the exact same thing over and over again, despite the adventure stages, I went to Classic, and loved it. It had three different bonuses, it followed the basic structure that SSB64 did (with the type of match) but it was random enough that you could play it multiple times in a row without getting bored. Same was true for All-Star, although I've never been a huge fan of it.
In Brawl, I don't like either of them very much. Both seem to drag on ad nauseam, and both seem too structured. All-Star is the exact same thing over and over again, and Classic is too predictable character-wise, which, while it may seem better to have the same than the type of match, makes it pretty boring. When the character changes, so does the stage. When the type of match changes, that's the only difference.
In any case, Classic has been lengthened and we have two Target Tests now. I mean honestly, does anyone enjoy that? It's not even as if you have diverse Target Tests anymore, if you play on the same level, you play the same Target Tests. No other bonuses to play, just those. All-Star takes way too long, because even though a lot of characters were mixed into one, a lot are also all alone. It takes too long, and it doesn't even change, so you can play it about once a day before you get bored. Also, I know I just complained about length, but why is it that you play versus all three of PT's Pokemon but not versus Zelda and Sheik/Samus and Zero Suit Samus?
All in all, I dislike both of them. The only good part is at least the All-Star trophies are worth getting. Last time they were just random poses with the characters in alternate costumes.
Which brings up another thing, why the heck do you need to play through each mode extra times with some characters to get all of the trophies? Zelda/Sheik came together last time.
