I'm sure the vast majority of us are here because they want a Banjo-Threeie by a different name. I'm sure not all of us hail them as beacons of perfection, and it would be nice to see Playtonic not repeat past mistakes.
For Banjo Kazooie:
Lone notes are frustrating and counterintuitive. The whole point of notes is to lead the player on a trail, giving a level a sense of direction. Having a look me note doesn't point the player anywhere, and if they get a note score of 99 finding that last one is just frustrating
The sole case of this is the note in front of the path up to the top of TTC.
No repeating content three times. The first three seasons of CCW aren't substantially different to warrant multiple climbs up the tree; multiple switches to alter the season for the sake of puzzles (not notes) without having to restart from the bottom of the tree would have been nice.
Lives are completely pointless. They're easily farmable, and all they do is make you redo Grunty's lair when you run out.
Ranged combat (shooting eggs) is taxed far too heavily. You're forced to stand still while shooting them, and on top of that they cost ammo. Being able to shoot while moving a la Mario's fireballs would provide a greater incentitive to use them, even if they still had the ammo cost.
For Banjo Tooie:
Notes are completely pointless. There's no point in the game where you need more than you have, there's no rationing like in N&B, and there's no benefit for finding large sums of them early in the game. If there's a number of ways of solving this, the first that comes to mind is having Jamjars appear to teach you a new move whenever you reach a new certain amount of notes, letting you access later moves earlier on in the game if you're avidly collecting notes. Speaking of moves...
Fewer context sensitive moves. You know what's a fun move? Being able to sacrifice combat for mobility via Talon Trot or the ability to attack in midair, period. You know what's not? Fire eggs that are almost never used for anything but blatantly obvious "USE FIRE EGGS HERE" situations. The boots, eggs, FPS-exclusive, and Kazooie launching move (which is almost exclusively just for breaking walls marked with her face) take up the majority of the abilities you learn. The only three BK had were the two boots and the spring launch pad.
Too many large expanses of nothing. Once you collect the notes from a road, most of the time it's devoid of collectibles.
Difficult minigames. The difference between a lovable shoot em up segment in a Kirby game or most of DK64's minigames and dreaded segments like Canary Mary and the morph ball bosses in Metroid Prime 2 is that the ones most players consider fun are relatively easy to complete. I'm not against having a difficult main game, but minigames are supposed to be fun, easy, short diversions. If you want their Pagies to be difficult to collect, just make the minigame difficult to reach, not complete.
Anyone else annoyed by anything?
DLC? UGANDA WILL NOT HAVE THIS SICKNESS!
