Illuminate - The track interacts well with buildings, and the terrain looks good, but it would have looked even better with more shrubbery, such as bulrushes and/or additional cacti. The supports are colorful, but I would suggest setting them up in a more organized layout so that they don't randomly alternate from purple tubes to red lattice supports. The brake run is supported nicely, and I like everything about the track except for the 2.9 lateral Gs, but that could be merely a result of the steep upward twist in the third screenshot. The excitement and intensity ratings confirm my belief that this would be a more thrilling coaster to ride than Povoat, and the layout seems more realistic.
Split Personality - This is the best support job I've seen on a splitting coaster, and the scenery is great down to the last detail. 5.9 vertical Gs is very high--the current record holder for operating coasters is 6.3--but it's the 4.4 lateral Gs that riders would find most unpleasant while riding, so it's important to bank all curves that the train travels through at more than 20 MPH, and make sure the higher speed curves have a wider radius. The terrain work around the lake is perfect for the spooky setting.
FANG - While this coaster wouldn't be too dangerous to ride, riders would frequently complain of pain after experiencing the 6.83 vertical Gs, which are probably generated by the two high-speed corkscrews (one of which is a cutback) after the brake run. Corkscrews are a great way to enhance any inverting coaster, but they should be saved for when the train is traveling at lower speeds. 28-38 MPH is ideal RCT corkscrew speed. Lateral Gs should ideally be below 2.5 and positive vertical Gs should be below 5. It's also important that the ride contain scenery, such as a station, a path, foliage, and if you really want to go for the realistic look that impresses Build It! voters, custom supports.
Dullahan - If I had to compare this to Highland Rumbler, this one is smoother and has a better layout. The scenery doesn't seem like much of a deviation from the other, but the scenery was flawless on that one, so why fix what isn't broken?
No complaints here, this is a grade A+ wooden coaster.
