Just beat the 8th world (not including post game content). Had a ton of fun so far and can't wait to dig deeper into post game stuff and going back to get all star coins and flag poles. (Well maybe not the flag poles so much, but it's something).
Game's difficulty definitely increased in the last two worlds. I reset once to make sure that the invincibility leaf didn't show up. Overall, it's been a great experience so far.
Now that a lot of people are playing this game:
- How long is the game?
- How many unlockables this game has?
- Is this game replayable?
-My clock currently shows a little under 5 hours, and that's with some idle time. Would say an average of 4-4.5 hours to beat World 8 with about half coins collected.
-A couple of major content unlockables, and a minor final unlockable (if you're familiar with Mario Galaxy 2, you'll kind of know what to expect, but not exactly)
-Definitely. Between all unlockables/extra content, dragon or star coins or whatever they're calling them, and trying to hit the top of extra flag pole (which is tracked), the game will keep you busy. From podcasts and reviews that I've seen, the average total time to unlock absolutely everything is about 20 hours.
