This is a great entree into a great RPG system. It's fast, rules-light, quick to teach and the full Deluxe version has enough bits to it to make it into a solid long-campaign rules system without losing the rules-light and fast play aspects.

The DM adventure included in this set is the one I use to introduce new players to the game all the time. It does a great job of showcasing the open-ended mechanics of Tunnels and Trolls. It plays great for new role players, as well as for those who are used to other system's ways of doing things.

The solo adventure included is also very good, showing off the game from that perspective as well. Someone completely new to T&T can play it on their own, and be ready to DM a game for others.

Side note: Tunnels and Trolls was the first game to use the term "Dungeon Master" in print. It was the second published RPG as well. I originally ran T&T as a one-shot or short filler campaign game system in the 70s, current versions are well suited to long campaigns.
