"Evochron" and "RiftSpace" have a freeform approach. In both games the player takes on the role of a mercenary pilot who is starting out in the universe and searching for wealth. The difference is in the way to gain wealth. In "RiftSpace", one will gather a wing to assist him, hopping from mission to mission with minor trading aspects. In "Evochron Alliance", the player is a lone wolf. The game is far more free in its approach and leaves the player fully free to explore, mine, trade, pirate etc.
