I actually bought this game, which at first I deemed as a mistake, well Two mistakes. I went to my local EB searching for a good new pokemon game for the DS also known as Mystery Dugeon, which at the time I wasn't aware that it sucked. When I noticed this game looked different than the others, is when I decided to go to the next best thing. The knock off of course, in other words Digimon World DS.
Unfortuanately Digimon World DS had not been in stock so I had purchased Pokemon Mystery Dugeon; which is the same repetive bull sh-t over and over again. After a week passed, the game was in stock and I went out to buy it, and it actually looked pretty good from the box. I play the game and it turns out to be a pretty good game, right up until I get to the battle system, story line, and same music used constantly. I can't put my finger on it but oddly enough I become overwhelmingly addicted, and now have over 50 hours on this damn game and have beat it completely.
TLDR; The game is barely average and is only worth playing for the Wi-Fi breeding system.
