I wouldn't exactly call this game new. It was awesome though.
It's an old DOS game, redone on the DS. It's my favorite of the roller coaster tycoon type games.
My only gripe with this game was the bugs. It had quite a few of them. One of which, which I hated the most, was visitors getting stuck in the wall near the gates at the beginning. It only happened on a very developed park. A visitor would get stuck there while walking towards the exit, and he'd stay there forever. Eventually all of your guests will get stuck there. You couldn't move them. You couldn't pick them up.
The problem that this created, is you could only have a set number of guests in your park. So eventually, nobody would enter your park anymore, since it was "full". It essentially was a park destroying bug.
Another problem that annoyed me was when visitors were exiting the park, they don't follow the roads. They'll walk over grass. Through rides. Whatever got them to the exit the fastest. This is partially what caused the bug I noted above (when they got stuck at the beginning, it was in the area on the grass that touched the wall and the gate).
Even with the bugs, this is still one of my favorite games.
You guys wanna know a tip? The first ride you should make is a large water tube ride. It'll skyrocket your popularity rating, and will bring in the customers. Place a few shops next to it, and customers will buy your stuff and make you tons of money.
