i actually like Nuts & Bolts a lot but if they do,do a sequel there are some things they will NEED to address!
but 1st off i think another nuts & bolt would do well especially with the minecraft/lego craze (my brother who loves both minecraft & lego is severely into banjo-kazooie nuts & bolts calling it super fun & although he thinks B-K was boring he also thinks B-T is like mario BUT WAY MORE FUN) so if they can marrie the nuts & bolts game play with the original B-K gameplay.
plus to anyone who says banjo's not about cars is plain wrong to because he has been in more vehicle based games then non-vehicle based games
diddy kong racing-a vehicle based racing game
banjo-tooie-platformer (he did transform into a car tho....& had FPS segments
(banjo-treeie-never happend T.T a soul crushing lie to promise a child!)
banjo-kazooie grungys revenge-platformer
banjo pilot-a plain racing game
banjo-kazooie nuts & bolts-a build a vehicle platform hybrid
sonic & sega all star rac
