As other reviewers have noted, the attention put into detail is enormous. It has many types of minigames, which should be revisited after the park characters give you certain quests, such as obtaining 5 forks for Ariel in an on-rails minigame you already cleared as part of a "Finding Nemo" attraction. Two player coop is drop in drop out, easy and satisfactory. With the latest XBOX system update, voice commands have started to work noticeably better, stepping up from getting a rough 40% OK to mostly 95% OK.
I advise you to install this game in the hard disk. Loading times are excessive sometimes, and can ultimately bore your kids. Not you, who have probably endured those Spectrum or MSX hard times with loading lapses of over 10 minutes back in the eighties. Some tech, eh?
Overall, this is a very good game, perhaps not perfect but it is as good as any kinect game can get to deal with something like disneyworld/land. You'll also find its price to be ridiculous after you discover the gigantic amount of detail put into those graphics, design, music and sound effects. This is a truly impressive effort, not a quick cash-in as some might, and should, think at first sight. The videogame market, as any market, is not an honest one, specially not today.
