Bandai's Digimon World series has had one or two ups, and lots and lots of downs. The newest title in the series, Data Squad, is more of an up than a down, but still fails to meet the expectations created by the first Digimon World.
This game is, without a doubt, the best looking Digimon game ever created. The cel shaded graphics are amazing and really convey the feeling of the anime perfectly. The overworld isn't amazing, but it looks better than most of the games out there today. The actual Digimon themsleves look extraordinary, and the first time you see ShineGreymon, you'll be blown away. It seriously has the best graphics of any Digimon World game.
Unfortunately, the sound is pretty average. The game uses the English voice actors, and all of the main Digimon voice their attacks in battle. The music fits the environment, but it's nothing memorable. The music is extremely techno, just to warn any techno-haters out there.
This game is a lot like a combination of Digimon World 2 and Digimon World 3. You've got three Digimon, and they level up and evolve as they reach certain levels. Unfortunately, the random battle rate is so high, it'll take you probably fifteen minutes to get across one screen just because you'll run into a lot of battle, which get pretty monotonous and repetitive by the end of the game. The game is pretty short, though, only around 15 hours, so you won't get too bored.
Honestly, like every other Digimon game on the market, you only really need to buy it if you're a fan. Digimon World: Data Squad was a great try, and it managed to beat out some of its predecessors, but it doesn't manage to be the best,
