RodBow, I must say, I agree with everything with you say as well.
I was also thinking today: the next game should just be more animated and "alive" in general, and make less use of static renders and graphics. Like, you know how the results screen has animated poses for every character, win or lose? Imagine if every character was animated like that in the pre-match loading screen, and they all had their own unique "ready to fight" poses.
This is what I'd like to see, not what I nessisarly think will happen.
A score based stock mode. So the person who lives the longest, isn't nessisarly the one who wins, but rather the person who managed to kill the most players before the game ends, with what is basicly a point bonus to the player who manages to still be alive at the end of the game.
The ability to modify how much score is awarded or lost when killing or dying in a score based mode. So say, you could lower the score for achieving a kill to 0 and let the score for deaths decide who wins the game.
I would like to see some charcters from the same franchise in the game rather than just one per. (technically theres two for infamous if you consider good/bad cole to be different characters) For instance, I'd like to see Dr. Nefarious as a playable character if they can find a good moveset for him. Now, I don't want just any character in the game like what happened in SSBB. Luigi, wolf, falco, toon link, ike and lucas, are all extra characters that shouldn't have been in the game in their state. (on the grounds of their gameplay being too similar to another character, if they had made each of these characters a bit more unique it would have been fine) Now I kinda think SSBB went a bit too far when allowing multiple characters of a single franchise into the game as a playable character, but as long as the sequal to psasbr doesn't overdo (IMO) it like they did, it should be fine.
Groovitron item, perhaps in the DLC for this game rather than waiting for the next game. For those of you who haven't played a ratchet and clank game, it is a disco ball that causes enemies to burst out into dance, allowing you to hit them freely.
Reworking of charcters. For example, I'd like to see ratchet as being more agile like he is in his games. Perhaps modifying his dodge to actually jump up into the air. He barely rolled around in any of his games, and certainly not his recent ones, whereas one I am constantly dodging in the majority of his games by doing an aerial flip to either side. I consider this to be iconic of ratchet.
I don't want charcters to be forced to have a "rival" to get into the game. It is a cool system, but I don't think a rivalry should be forced apon characters that it wouldn't make sense on.
More "precise" customization. Say, being able to choose several features of your current costume without switching out the outfit. For instance, if they add in isaac clark from dead space, you could choose whether or not he removes his helmet in taunts, all the time, or not at all. Perhaps being able to mix and match different pieces of many costumes into a single one.
A more in depth story mode, with more than random fights to it, but keeping the rivarly concept, maybie some allies?
More characters, but do not remove any character in game that made it in ( including DLC )
Unlockable characters and stages
More stages, each character with a representation stage
Capture the flag and king of the hill
I really wish they focus a little more on single player if there's a sequel.
The reason I liked Brawl so much was the subspace emissary mode. But don't get me wrong I do like playing in the arcade mode but it's always nice to have a more "dynamic" story mode than simply a line of characters for you to beat up.
As for characters I really can't say much... I liked this roster (except for Kratos, Raiden and Radec) but it would be nice to see Snake, Sora or Roxas and some FF rep.
For new stages I'd love to see a Metal Gear / inFamous stage can't imagine a cool concept for it though...
Well they should also make some improvements on the online multiplayer, I've seen lots of people complaining about lag issues and connection problems. I had some bad experiences with it too, like taking more than 2 hours to find people on quick match.
Anyway those are my thoughts.
I would hope for revamped Supers. It would be cool if they changed everyones Supers or at least make them a bit different.
All the other stuff is obvious, new stages, new characters, etc.
I would also hope for better and more rewarding unlockables, give us something for committing to a character and making it to Level 999. Also let us customize the menus? Maybe give us the option to choose backgrounds that include the rivals eyeing each other out, example: Spike and Parappa up close looking at each other and Spike has his Stun clubs aimed at Parappa while Parappa has his fist towards Spike. The background would flash, and move slightly, maybe make their eyes flash, something.
I don't even know if they'll make a sequel after these sales, and if they will, it'll be incredibly low-budget like PSABR, and another mediocre game overall. At this point I would make a kart game à la Crash Team Racing like someone suggested here, it's easier and has more potential.
