Begun in 1992 in partnership between Electronic Arts (who own the rights to the Starflight franchise) & Tsunami Media and touted unofficially as 'Starflight 3', Tsunami went on to finish the game and publish it on their own as 'Protostar: War on the Frontier'.
"[Protostar] blends elements of role-playing, space exploration, space combat, and resource-management. The player commands a spaceship from a first-person perspective in real-time capable of traveling to the various planets of a galactic sector and launching an explorer vessel to traverse their surfaces. Several sentient alien races inhabit the region with whom the player interacts through diplomatic conversation, intense spaceship combat, or barter at their planetary trading posts. The player has been recruited to convince the other sentient races in the region to join humanity in an alliance against aggressive aliens threatening to conquer the Earth. A secondary goal of the game is to earn money by performing actions such as selling alien lifeforms and minerals collected on planetary surfaces to obtain the funds needed to upgrade the player's spaceship and improve the odds of survival in confrontations with the aliens and other hostile entities."

Protostar implements a rather attractive and innovative (for the time) point-and-click graphical UI display with hotkeys, arguably a big improvement over (or alternatively a pretty re-skin of) the two inspirational earlier Starflight precursors by EA/Binary Systems. It also features an early example of real-time 3D space combat presented on a 2D tactical display, which provides an awkward yet notable video-game experience in its own right. Although smaller in scope and missing such things as alien artifacts, it still largely retains the same game experience 'feel' as its conceptual cousins.
