Summary: The game has a decent collection of mini-games for groups. The problem is so does Wii Sports, the main competition for this game. Plus, Wii Sports comes bundled in with the Wii for no extra cost. Overall, this is a game that is worth a look from groups looking for something new. For everyone else, look for Wii sports fun elsewhere.
Conclusion: It's impossible to fault Hudson for wanting to tap into Nintendo's success of the Wii Sports franchise. Unfortunately, the publisher seems to have missed the forest for the trees. Putting style above substance, Deca Sports 2 looks a lot like Wii Sports on the surface, but that spark of magic just isn't present here. One or two of the minis can be fun in short sittings (especially with friends), but on the whole, it's a package that lacks a solid fun factor.
