personaly, i thuink fh is better. heres why
arokai has (as far as i know)...
lots of animal choices
a public map for all to play on
(feel free to add to this or correct me)
fh has...
presets
map making
private maps for better roleplays
four public maps
the ability to add friends, whisper them, and find them ingame eisier
lots of fun people to hang out, rp, play, or just chat with (im sure this will also be on arokai)
