Hmm... Brawl 2?
I figure they're just thinking of making it so there's a Subspace Emissary sequel. Not that that's necessarily a bad thing. In my mind, only a few things bothered me about Adventure Mode:
1. Lack of enemies from the actual games...
...random, creepy-looking enemies from out of no-where doesn't work, IMO. Mario was the only one that got enemies from his game series. What was up with that? Not to mention he doesn't even fight them.
2. It's overall shortness..
..I'm sure they just didn't want to delay it much longer, so it's pretty good, actually, so I didn't actually mind the shortness as much as what they did to make up for it. Final stage- ok, let's take everything you JUST did and make you do it all over again, plus harder and more confusing. sound good? O_o Great Maze = epic failure, imo.
3. Lack of Boss Battles..
...even though more bosses would've made Boss Battles mode much harder.. I'm disappointed that out of the 10 bosses there are, only 5, yes, half of them, are from actual games. Think of all the bosses that could have been, but weren't because they decided to make up characters like Duon ..and the other dude you fight twice that almost kills Lucas and Pokemon Trainer. Come on! Where's the koopa kids, Medusa, Twinrova or Majora. Tabuu was actually a character I was ok with, but I just would have liked it better had be been more involved in the story.. which brings me to my next point.
4. Storyline makes little to no sense..
...ok wtf no one talks? Half the time I don't even know what's going on. And everything's completely random. Love that. Yep, I don't need much of an explanation for this.
Yeah I think I should stop now, I'll bet like no one reads this anyway. I think think they could've done so much better on SSE or just done without it.
