I've finished
Fairy Fencer F today, or rather decided to abandon my futile quest to 100% it, that's why
106 hours played, about 30 of those were grinding if not more
these are missing achievements
these are my stats after 3 playthroughs and 106 hours
more than 2K battles still to go
and more than 70 mln in cash to get!
those are not even worst, there are ingame challenges for every character that I cleared maybe 10% of those. IF decided to outdo even tri-Ace (their games are pain in the ass to 100%) and I think they succeeded. All IF games have some hard to get achievements or things but FFF ones are outrageous.
don't repeat my mistake folks, go for fun and play the game, don't bother with perfect things in this particular case.
I will write a review later too.
