Like all Harvest Moon series its always hard at the beginning. It wouldn't be a problem if Rune Factory would follow pattern known from Harvest Moon series. But it doesn't. They added "lame" combat to it and made growing crops daunting, depressing task.
First combat - it's simple button masher where you either : A - Attack, B - run ( or if you stay, die ). There isn't any way to block and there is only one special move to each weapon. So combat is very basic and poorly made. Didn't enjoy it. I would expect some sophisticated blocking, dodging skills but no... it's either run or attack... Which is boring after a while.
Growing Crops - Lots of new player neglect "runeys" a little glowing creatures, at the beginning of the game. Doing so they decrease quality of the crops and the speed of growing. After few months in some regions runeys are dead and your crops grow TWICE much longer and Lots of them whither ( die... ). So if you want a good farm grab a harvester and distribute runeys in each region of the town... WHICH IS A PAIN! Once you've done that money isn't a problem. Just plant most expensive crops to get loads of cash . Soon you will buy everything that is possible to buy.
Story is a little bit lame... But characters makes up for lack of good story line. There are many responses for each character unlike Harvest Moon series where characters had 2-3 lines that repeated all the time. So basically more chatter :) It's fun to impress the ladies in this game, but it can be daunting task if you want to get them all at 10 heart...
Graphically it's way better than any other harvest moon series! Very nice backgrounds, characters animation, it's just great! Compared to hravest moon : tree of tranqulity... boy that was blank... So yeah the world is big, so there is plenty to do and discover. I also liked making new tools and accessories in this game. Some materials are TOO hard to get... like little crystal. That was a pain in the neck.
You will get frustrated many times with this game. So it's advisable to get a FAQ or Walkrthough before you start playing. If I had done that I would avoid many mistakes...
Overall - it's better then Harvest Moon series in many ways! But it's unpolished and many cranky ideas that doesn't work... stupid runeys hate them....
3/5 - No more no less. Try buy it for cheaper :)
