You have to assemble a lot of clues to figure out some situations. Easy doesn't have to mean simplistic any more than it has to mean boring. The pacing was good, is what I finally decided. You don't find a puzzle A and clue A, followed by puzzle B and clue B, and so on. That game-shape is either boring or frustrating, depending on whether you breeze through each puzzle or get stuck somewhere along the line.
ROTS is much broader than that.
You get a bunch of puzzles and a bunch of clues, and when you solve a couple of puzzles you get a whole bunch more puzzles and clues, and all the time you're exploring new areas and seeing more stuff. You have a very wide range of options to check out, most of the time. The puzzles happen, but because they're pretty easy, you don't spend a lot of time working on them, stuck and frustrated. You either know what to do, or you know that you either need more info. That praised, let me talk about some flaws.
