ok, i have the majority of coaster games (except disny and ultimate ride). I have to say no limits has more trakcs, and better graphics. Also the sounds in nolimits are surpurb and you have a better "sense of speed" than in hyperrails. The editor in both games can be a bit confusing, for one, no limits has a seperate editor from the simulation, and its wireframe. You have different views, top, left, right, front back, and 3d. Hyper rails is totaly in 3d. In no limits, you click to add a track segment any where, the shape of the track depends on where the previous track node is and where the next one is, of course you can alter it and change it around to whatever you like. In hyper rails, you click add, and it will add a srait peice of track then you shape it to the way you like. I would say hyper rails' editor is a bit easy to get used to, but no limits' editor isnt hard to use. You can make much smoother coasters in no limits (in my opinion). For the graphics and such, go to
www.nolimitscoaster.com and download the demo. You can mess around in the editor, but you cant save! So only thing you can ride are the rides that are there. I know, when you first start to use the editor, its like WHAT THE HECK! But trust me, mess around and study the other rides, see how they are built and try to mimic them, but just try everything to see what each button does. There is a help guid ( not sure if it is with the demo) incase you are just totally lost. When i bought no limits, it took me around 1 week to get the editer down and design descent rides. Hyperrails, it took me a while to figure out the brakes and blocks, and its not that easy to make coasters as smooth as you could in no limits. If you are thinking about screammachines, i suggest you download that demo too to see if it will run because that game requires a pretty up to date computer. For as the editor for screammchines, its very simular to no limits, only it isnt a seperate program. Screammachines also has just about every track style, but as i said, download the demo to see if its for you. Overal, no limits IS the better buy. Download both screammachines and no limits to see which you like better. Sadly there is no demo for hyper rails, i beleive, but the requirements are about the same as no limits.
