Camera issues aside, this game is fun for one or the whole family.
Starting off, the game gives you a decent amount of options to customize your avatar, ranging from little kids to older teenagers, boy and girl, with varying styles of dress that will please goth and preppy alike. This is what sets this game apart from other theme park games: You are in the park, walking around as someone that the park goers can directly speak to. Once you pick your other self, you are literally dropped into your new theme park to do what you wish (after some short tutorials, of course). From then on, the park is what you make of it.
And what you make of it is vast and varied. You get to decide from a good range of different rollercoasters, carny games, drink stalls, food stalls, and arcade games, all of which you can walk right up to and use. The various missions your lead inventor gives you are fun and intuitive. Most mission descriptions will either warp you to the person you need to speak to, start the game you need to win, or at the very least, give you a good indication as to what the game expects of you. My only complaint with the single-player game is that the camera gets stuck on things when you rotate it.
There is also a party mode that you and your friends can jump into and includes any games you have unlocked in the single-player portion of the game. These consist of various flash-type games and shooters akin to 1942, along with DDR-type games and carny rides.
