If you would enjoy exploring the depths of space, you can do this from the comfort of your desk chair. Even if we will not travel through space during our lifetimes, we can still play great games like Wazzal and have a great adventurous experience.
Wazzal is a space adventure game in which you have to trade different materials and also protect yourself against bandits. As you gain more money and ships, you will be able to build a full fleet of ships in order to become a powerful person. Watch out for those bigger than you who want to fight, though.
