Darkstar One

Currently playing Darkstar One (wiki), released on June 16, 2006 by Ascaron.

It is another freeroam space combat/trading/bounty hunting sim just like Freelancer, Privateer, and X3: Reunion (or the X series). Unlike the other games, you only have one ship (you cannot buy another) but because of this, you can upgrade your ship from a high-end combat fighter/freighter to a super- or very-high-end and powerful ship. Confused? Well from the start of the game, your ship dubbed the "Darkstar One" is an experimental and 'already' powerful vessel (hence the high-end description above). This experimental state-of-the-art craft can collect artifacts scattered all over the game's space in order to gain the next level or level up.

I think I will be stuck in my room for a week or so for this. Off to my bounty!
