Thrilleville Off the Rails was a bit of a disappointment...
The idea itself is kinda new I guess...but they basically just took the idea of a theme park simulator and turned it into a more action-type game, which isn't necessarily good... I actually did like the idea of building your own coaster (even though plenty of games have used that), but I especially liked the "Whoa!" parts.
The biggest difference that I saw between this game and the first one is new "Whoa!" parts. My favorite is probably the one where the coaster goes off a ramp and lands on the track again after flying many feet in the air (it goes "Off the Rails!"). But once again, that was the biggest difference I saw in the two games, so if you own Thrillville (the first), and you think "Whoa!" parts are worth it, go ahead!
Next, the use of the Wii remote.....
Honestly, I haven't played many games that rely on special movements in very specific directions, but of the few I have played, this one is by far the worst. You won't be using the Wiimote too often, but when you do, it can be a pain. You will probably use the remote the most when you are designing your own roller coaster/race track. This can get annoying to the point of not even wanting to bother designing your own coaster.
What you have to do is use the remote to direct which direction the track piece will go (up, down, left, right) by aiming the remote. You can also bank the track by tilting the nunchuk. Sounds easy maybe? Or maybe now that you're hearing this you are having second thoughts...well its annoying, like I said. When you want it to go up, it's straight; when you want it to go straight its up.
The wiimote is also used in many of the mini-games that you will play. These games are mostly fun I must admit. This is probably my favorite part about Thrillville/Thrillville Off the Rails. Unfortunately, as expected, there's a problem. Though many of the games do work fine, there's those few that just don't want to cooperate. One that I will never forget is "Alley Ball".
In this mini-game, you have to use the remote the throw a ball up a ramp and into specified holes. This may seem a bit reminiscent of Wii Sports bowling. The problem is, while aiming with the remote, you get no indication of where you are aiming. No crosshairs, target, reticule, nothing. So, basically you are blindly throwing these little balls into holes at high speeds. Another bad thing? You cannot see how much power you are using until after the ball is released.
So, I thought that would be alright anyway, even though I was still a little angry. I tried throwing to the left, the ball goes completely to the right. I tried throwing to the right, and I see the ball go right down the middle. Luckily, when trying to throw down the middle, you usually meet with success, with the exception of a few stray wanderers.
So what's my point? Well, I would recommend that you don't even touch the game, unless it still sounds entertaining, then I would say rent it first. It can be a fun game, mostly the mini-games, or else I would have rated it between 0 - 3, but you probably shouldn't waste your money.
