Okay, so you are curious about buying this product? If yes, please read this before making your decision.
1. NoLimits 2 is a fantastic piece of software, yeah, software, because, according to the makers, they are targeting realism now and they prever to call it a simulation-program. Keep in mind this ISIN'T RollerCoaster Tycoon or Thrillville.
2. You can't be a sadistic a-hole and watch people die, 2 reasons: there aren't any peeps in the entire simulation, just steel, wood and foliage. The second reason is that you can't crash a coaster, if it hit's the end of the open track it just displays and error stating that the coaster has crashed.
3. If you want to make rollercoasters, of course you do, you have to learn it. It's not that you build gorgeous tracks within the first hour, propably not even after 10 hours of learning. There aren't track-pieces like RollerCoaster Tycoon, it's more CAD-style based, just open air. Actually it's an editor where you can design almost anything inside.
4. You can add buildings, etc. to it, but you have to make them in a program like SketchUp, 3DSMAX, etc. Than you have to export -> import them. As you see, this is not a game for people who don't have patient, this is a quality program which is rather serious. (Although they have an annual April fools joke on the news-website)
If you like building rollercoasters and would invest some time in it to use the same software as some of the professionals use, don't hasitate and buy this gorgeous piece of art!!! If you like rollercoasters to ride them, buy it also, on the market-place and other sources like coastercrazy, nolimits-exchange, etc. you can have an almost unlimited supply of coaster-food. Do you want to build coaster in the simple RollerCoaster Tycoon site and don't want to learn how you make proper creations, yeah, better spend your money on something better. Although this software just deserves to be bought anyways.
