What is "riftspace"

RiftSpace is a space exploration and combat game for PC first released in 2004 by StarWraith 3D Games LLC. RiftSpace was released almost simultaneously with Star Wraith IV: Reviction. Whereas the Star Wraith series prior to the release of Riftspace in 2004 had been purely military, RiftSpace is a freeform mercenary game. Its successor is the Evochron franchise, none of which were or are freeware games.
