Maybe you guys look at it from the wrong side?
You shouldnt look at the similiarity of those games but why they are made.
IT and FH also Arokai are made cause the creator do have fun with these and love to improve their skills. Also IT was once made for a special person in Kovus life, and this little game grew more than he was expecting it would do.
However, FH is not to be planned to be an big online MMORPG, it was started with this idea but Kovu does not have the time to make that happen anytime //soon.
Arokai has a clear concept for the game, compared to FH that is made just for having fun.
Its not like the big run against each other of who developes the best, the fastes and what so ever anything you can think of.
I really love that there are now so many different games, some arent up running yet, but its nice to have different feelings and flairs in the different games. For me they are all not the same.
