Although I found myself spending a few nights staying up late wandering Avernum and trying to complete some tasks, I still do not like the game genre itself. It is too much work and not relaxing. However, I am sure any fan of RPGs will like Avernum. It is a vast world with many characters to interact with, whether to engage in battle or to get help.
There are plenty of things to find to equip your characters with, and they can also improve their skills through learning or trading. If you want, you can carry out side tasks while you try to perform your duties.
