There are a lot of differences between the original Cthangband 2, but the two games are similar in many ways. The main differences between the two games are in how they handle explosive monsters, and in how you level your character. Angband has a single-player mode, while Cthangband offers two different types. Each has different advantages and disadvantages. Regardless of your preference, you should check out both games before making a decision.
The first thing that sets Cthangband apart from other RPGs is its lack of character classes. Instead, your character will start off as a "template," which provides an initial set of skills and equipment. This means that there are no restrictions on what skills and equipment a character can have, and this makes it extremely flexible. A Mage can study magic without any restrictions, while a Swashbuckler can learn to fight with no limitations.
Another major change is that Cthangband has new character classes and races. The game has also been in development for twenty years, so the content is very well designed. As such, it is a great variant of Angband. This article will focus on the differences between the two games. You can read more about the differences and similarities between them. So, you should give it a try. You'll never regret it.
