This was probably my favorite theme park game to play as a child. I started playing it at the age of nine, unfortunately, computers since then couldn't work it very well and it's probably because it's a very old game. I have been wanting to play it for a long time since like 10 but it never would work. As a child, I loved theme park games as well as riding on actual amusement park rides.
When I got it up working now in 2017, I can see that the game's graphics probably are dated at this time and I recognized that the adviser's got some sort of British accent or something in his voice, and his voice acting was OK. It's been a long time since I played the game, though. The adviser is some sort of ant or alien or whatever who pops up to help guide you through the park.
I don't understand why he keeps clearing his throat every time he disappears and he can get annoying sometimes constantly saying "You employees aren't patrolling the area" or "your visitors are hungry and thirsty". This is also evident in another theme park building game called "Theme Park DS", where your assistants keep popping up telling you the same annoying thing.
The cutscenes from what I recall has the kids causing trouble so they're nothing interesting. Anyway, the play style is really quite fun and very simple. Maybe a bit complex, but it shouldn't be too hard for kids as long as they know about building games. Building great rides is easy.
I don't know if a lot of people know about this, but I always loved this game and some of the characterization was memorable, too. It has features some other great theme park games don't have such as camera mode. Give this a try if you haven't played this already. You might be surprised.
