Although a little simple, it has an ok point system and presents a challenge. Needs an intro, a point to the game. Also have the ability to choose your name in-game and an online multi player version.
The harvesting system takes a little bit to get use to, but if you master it you realize its not all that hard. Only problem I see is units attack a little to slow in comparison to monsters.
@Durlock i get lucky coins from bosses who are higher level than me, for example, my level 30 chimera beats first boss with 1 hit and i get 2 lucky coins. Other party members are at least level 25.
Needs a level system, so you can tell how long a person has been playing. I often go against people with less than 200 rating that kick ass, and I also often beat people with over 2k rating.
