Karoo was my one of my favorite since I could finally use my legend to farm (yeah I also use him on my striker team but I meant more as captain). It was too easy though.I actually did that with my collection of usopps for golden pound, but ended up lucky on my skill ups.
Due to that I now have 4 golden pounds.
/edit
btw this current fortnight being an absolute bore in terms of content got me wondering..
What's everyone's top 3 fortnights so far?
So I'm thinking the fortnight "as a whole" in terms of books, characters, additional rewards, artwork etc.
for me it's:
3. Karoo
You know what sucks? Having to grind old fortnights from the first week or two for vital books like Alvida or Usopp.
Having one of those ultra-essential books show up in one of the weirdest fortnights is honestly a treat. The HP cut gimmick really makes for an unconventional challenge as you wade through hoards and hoards of enemies, hoping desperately for that weird grasshopper to show up.
Two super important books, golden pound & marco + a really unique gimmick made this a great fortnight for me.
2.Twilight part 1.
As I was going through the list there's definitely a lot of fun fortnights, but very few were as strong in content and theme as this one. A fortnight that allows you to capture fun variants of a large chunk of the crew, still a bit of challenge & possible ways to screw up .. and it gives access to a large number of important skill books; including some legendary ones.
Honestly what could beat this?
1. Twilight party 2!
The answer ... holy smokes this one was fun.
How do you improve on Twilight party 1? Simple: Give us more of the same but make the boss strawhat actually legitimately viable.
Halloween zoro's got surprisingly slick stats for a turn delayer, the books given are largely even better than HP1. What's not to like?zoro's skill failing 20 times in a row.
The other fortnight I'm really enjoying now is Kimono Jinbe on Japan. I'm not too sure if its due to how hard it is (since I have to build my team around low cost due my low pirate level) or the characters themselves. The G orbs are also a cool mechanic as well and the bombs forces me to be on my toes.
