I used to play this game when I was a kid. Back then, I relied heavily on the Hint Book that came with the CD; then again, I was also 8 years old.
There are 3 paths that one can "choose" from based on early actions and dialogue in the game: The Fists Path, the Team Path, and the Wits Path. My favorite of these three is the Team Path, simply because it seems to provide situations privy to having the largest amount of sarcastic dialogue classic to the Indiana Jones franchise. It's the only path where Sophia Hapgood (the female character) joins you for the entire time, and thus gives you an AI teammate (who has a witty demeanor quite similar to that of Marion Ravenwood).
I always feel like dialogue is the most enjoyable part of a point and click style game - especially the old DOS ones - and can definitely make or break it. This is one of my favorite games for this reason; it does a very good job staying true to the feel of the movies and really deserves it's unnoficial title of Indiana Jones 4.
If you're looking for a fast paced adventure game, this is not it. While a lot of the puzzler-type aspects can be very difficult without the use of the Hint Guide (obviously not included on Steam), fighting is optional and with the limited point-click method - not very engaging, so I wouldn't reccomend that. The puzzler aspects include using objects with one another from multiple locations and working out persuasive dialogue paths.
All in all, I would have given this game an 9/10 in the late 90's, but as it is 2014, (but I'm still nastalgic) I'd say it's a 8/10 (mostly because the DOS-style pixilizated art now drives me nuts).
