Like many similar games,
Sister's Secrecy: Arcanum Bloodlines gives you inventory items when you complete a hidden object screen. These are used in the game's other puzzles, but for those gamers who don't like the adventure aspect, anything beyond the standard inventory-based puzzles will let you skip them after a bit of time. For instance, puzzles that involve simply using the right tool for the job are typically helped along by the hints given based on the difficulty setting you chose, but puzzles like determining exactly how to mix that dragon's cocktail or piecing together a stage coach ticket will give you some time to work on it, but eventually let you carry on so as not to slow you down too much.
These bits of gameplay flexibility really impressed me, and while I feel like the game's story is interesting and fairly compelling, at least what I've seen of it so far, it is these gameplay options that really make Sister's Secrecy: Arcanum Bloodlines appealing to a wider variety of gamers than just the ones that like both genres. With these options, even gamers who prefer one genre over the other will be able to approach this game. If you find yourself even mildly interested in either genre, then definitely keep an eye out for Sister's Secrecy.
