The 3DS version is quite different fom the Wii U one so I was recommended to create a new topic for it.
Anyway, Sonic Lost World 3DS have 4 modes of playing the game:
"Play game"Basically story mode. Saves your best time, score, red rings and rank. Lets you use items and RC stuff. This mode lets you use super sonic I'm pretty sure (haven't unlocked him personally).
"VS mode"Lets you play through stages and special stages. Doesn't save scores other than ranking. Also has a battle mode where you collect rings.
"Time attack"Only saves your time, doesn't allow items/RC. I think colours are unlocked based on your progress in the main game.
"Hard"Available in main game and time attack, has separate charts but I don't think there's any major changes other than you only having 1 ring throughout the stage.
Small stuff:Checkpoints don't reset your time. Timer goes down instead of up in story mode or whatever. You can't submit your time from story mode to the leaderboards which also means the WH tutorial stage can't be submitted. Lava mountain is basically "Boss rush zone" so I don't think anything other than times would be meaningful to track
Trackable stats:Time attackStandard time attack done from the time attack mode. Would restrict using RC's, super etc. Also excludes the tutorial stage
ScoreTracked in the main game only. Would allow RC's, items and possibly super if you go by the score that's saved.
RingsNormal ring attack, could be done without restrictions I guess. Have to be decided upon.
SuperI personally dislike this as you basically just go faster. We'll have to see if the IL's become different enough. Decreases rings etc so I think it would only be useful for time attacks.
HardDumb... But it is tracked on the official leaderboards.
