It's time to GET DIGITAL...and meet new friends...LET'S GO TO THE DIGITAL WORLD...
The storyline in this revolves around you the player and you can be male or female. Similar to pokemon you have to level your digimon up with certain conditions to be able to digivolve into one of the next forms of the digimon you are raising. After you find the researcher Phil you are able to Return a higher level digimon to a earlier form to re raise it to a higher level to get another type of digimon in that line that's more powerful and can also grow more.
There is a growth limit set into each digimon you raise regardless of level. This is based on the amount of data that you have collected of that digimon before you convert that data to the digimon itself. Each time you graduate to a higher level digimon that growth limit does change depending on the type of digimon it evolved to. However if when you're in the higher level you won't have enough to make it to the next level available for it you can deevolve to earlier forms as stated earlier if you've collected more data with them in your party. This will allow you to later re evolve the digimon to something better.
The farm concept is great though that and breeding really shines in wi fi. I don't have a wi fi connection myself but i know that's how you get the most out of the farms you get. You can have a total of four farms and as in harvest moon you are allowed to pay for size upgrades and buy goods for the farm in the way of training equipment for the digimon.
Some of the missions are time consuming because you have to figure out which direction to go in to reach your objectives but it's worth it and you get to level your digimon as you figure it out.
So have fun with this game i think you'll be pleased because it's the first decent digimon game that i have played and actually have wanted to take through to the end.
