There is now release available for Open Realm of Stars:

https://github.com/tuomount/Open-Realms-of-Stars/releases/tag/open-realm-of-stars-0-0-6Alpha

Biggest change to previous release is now game has diplomacy between both AI and human players. AI players now also have attiribute called attitude which is used to make decision in diplomacy and what is AI is going to build next. For example AI with aggressive attitude starts war more easily than for example peaceful. Scientific attitude on other hand tries to trade or buy technology from other players.

Since there is diplomacy possible in game, there is separate relation view where one can look all the relations:

Idea for this relation screen is from old game called Warlords 2. So relation status between players can be unknow, peace, war, trade alliance and alliance. First three are quite obvious. Trade alliance means that non military ships can travel other players sectors and alliance is where all ships can travel on those sectors. 

OROS now has two new space races: Mothoids and Teuthidaes.

Mothoids are Moth looking(Image by Surt) creatures which grow very rapidly.

Teuthidaes are squide like mosters(Again, thanks to Surt) which have built in cloaking devices in all ships. So yes this version also has working cloaking devices and scanners. AI is still missing "mission" that it would do espionage towards other players.

Screenshot about all Space races:

And finally screenshot about the diplomacy screen itself:

ghrl.png looks better to me, but it is mostly because general.png has arm and leg in a funny position compared to ghrl. Altough I like the sword more in general.png. Making game requires a lot of graphics I would choose which ever would be easier to draw for you. Especially if you plan making all the graphics by yourself.

Hmm, it has been while since I have posted info here about Open Realm of Stars. Game now has menu clicking sounds, combat sounds. Also each alien race has their unique spaceship arts. There are couple of new screens too: Stats screen which tells about player planets, population, military power and so on. There is also planet invasion screen where attacker can bomb the planet or use ground troops to occupy it. Defender automatically shoots with planetary turrets if there are any. There have been quite much bug fixing and improving the AI.

Then couple of new screen shots:
