No Limits 2 is hands-down the best roller coaster program I've used. It has a nearly endless seeming list of new features, most of which make things a whole lot easier than No Limits 1. There really is no competition. It's like comparing school cafeteria food to Olive Garden. It took 8 years but it was worth the wait.
I really like how much easier the building system is compared to NL1. That's one of my favorite things about NL2. That combined with auto-heartlining the track, I feel like I can build any sequence of curves how I want, in any shape. I don't really feel the need to look back or live in the past.
The graphics, while not a top priority for me, were made with TLC. The terrain editing, environments, and tree models pretty much encourage the user to make the most of it, particularly if they're designing a terrain coaster.
The combs, while not exact, give an indication of how I'm doing at making the ride survivable and smooth, and help take away more of the artificial difficulty that NL1 had. Having multiple viewports is slightly awkward but I can watch the G's of one viewport while watching the radii in the other. With this much in the way of new features to aid in smooth design, I feel like I can comfortably stick with hand-building, not even think about touching FVD++ (no offense Lenny). I really wanted to make smooth, heart-lined track and be able to easily adjust earlier portions at will if needed, and now I can.
The NL2MAT editor is pretty complicated for me, and I'm not sure if any adequate tutorials for that exist. Of course, scripting is even more complicated for me. I really like the scripting engine allows one to use custom trains. In fact, the attachment script is so versatile one can use it for custom trains, attaching headlights, automobiles, Tin Lizzies-type rides, Raging Rapids River Rides, etc. And this is just one little script. Too bad the scripting language is too complicated for most users.
As awesome as this program is, there are a few things I don't like.
-If I forget which park had a particular coaster I want to work on, I have to open and check each park. Search bar won't do.
-Testing the ride just in the editor seems to have been removed.
-G-force combs ignore dive machine holding brakes.
-Importing an element makes all the roll nodes 'strict' so I have to uncheck 'strict' on at least most of them. Might be a bug.
Overall I recommend this game for any roller coaster enthusiast, and anyone who wants to make virtual coasters but finds NL1 too hard. Even if you're not a die-hard fan and don't know the names of the manufacturers or if you don't ride roller coasters very often, I feel like the sequel difficulty drop may be enough that you just might enjoy it anyway to at least some extent.
