A different 4x game as it only set in one solar system.
Got a kickstart going at the moment, still has 18 days to run, looking for a modest $12,000

• Full-scale star system: The entire system is built at a realistic scale. Zoom seamlessly between a close-up view of an individual ship and a strategic view of the star system. There's not a loading screen to be found.
• Customizable ships, weapons and modules: Build everything to suit your tactics. Create each ship and every piece of equipment from plans you create through research.
• Real-time tactical combat: Command fleets of up to a hundred ships each in real-time battles. Take control at fleet, wing and ship level and lead your forces to victory.
• Complex strategy: There are only a few resources, but you'll have plenty of challenges in managing their extraction and use. A huge variety of possible ship roles makes it vital to learn about your enemy so you can manage your fleet composition and deployment effectively.
• The best of both worlds: Get the depth and variety of turn-based strategy and the adrenaline of real-time combat. There's a lot to think about, but non-combat tasks like research and production can be handled with the action suspended. Simultaneous battles, however, will demand your simultaneous attention.
