The short version review is this: if you like the Point & Click genre, you will most likely enjoy this.
What are pros for some people may be cons for another, so here are some general points to consider:
*Puzzles are the usual P&C fare, meaning not always intuitive in terms of solution. If you already enjoy the genre, you already know this and it won't bother you much. If you are newer to the genre, you just have to remember the all-purpose "click on everything" rule and "combine your inventory with anything you can no matter how strange it seems" rule. There's nothing too farfetched.
*Voice acting is quite good for the most part and the interactions are fully voiced, which I appreciate. Sound and music in general is nicely done.
*Art is very cartoon-ish. That could be a selling point for somel; it certainly isn't for me. However, despite being sort of a snob about art style, I will say that it is very well done even though it's not a style I love. It in no way detracted from the overall game for me, and some people might absolutely love it.
*The story was good, taking our heroes into Mayan Central America this time. The end was a bit abrupt but did tie up the story nicely. The addition of some optional graphic novel content helps flesh out the gap between this game and its predecessor.
*There is a built-in help system for when you get stuck, which you can choose to use if you like (or can ignore, if you like!). The help is "progressive hint" style, giving you the option to start with a very vague hint and work your way up to a detailed solution if you're still stuck. While some people consider this absolute heresy, others will appreciate not having to track down a detailed walkthrough for help on one small point.
*Play time is shorter than some comparable games. I clocked in at around six hours, plowing straight through and not getting too hung up on anything (I'm too impatient to wait too long before checking to see what I missed!). For someone not using any hints, it could probably take a couple hours longer.
So, I would recommend not only this game, but picking up the trilogy in a package if you don't have any of the games already. It's a great deal and definitely worth it.
