Evaluation

Space Trader: Merchant Marine launched on October 23, 2008. There are no post-launch updates, patches, expansions, or DLC of any kind on record. The two developer news posts found are entirely unrelated to this game — they concern the developer's separate "Murder Is Game Over" mystery game series. The developer has not communicated anything about Space Trader since its release. With no post-launch content history and no announced plans, this game launched as a complete, standalone product and has remained unchanged since its original release date.

Evidence

Store description presents a complete game premise with no mention of planned updates, DLC, or ongoing content development.

Developer post is a retrospective about the Murder Is Game Over series and announces a fourth game in that series. Entirely unrelated to Space Trader: Merchant Marine.

About this game

In the far future, humanity is ruled by The Ministry of Accounts, an oppressive bureaucracy that tracks, records and taxes every transaction of daily life. From the depths of Red Tape, a new breed of marketeer arises to challenge the authority and make a profit: the Space Trader is born!

As a Trader, you will attempt to amass a fortune beyond your wildest imagination, buying and selling commodities and taking up arms against the oppressors or even accepting bounty missions, hunting down crime bosses and their thugs.
