Empty Spaces is an open-world 2D space sim with realistic physics, electromagnetic emissions and sensors model (esm/irst/radar/visual), thermodynamic model (heat/irradiation/sun), damage model (penetration/fragmentation), power model (production/consumption), and of course newtonian physics and navigation.

You start with a rusty bucket, some debt, and a sector that doesn't care you showed up. You mine, haul, take contracts, upgrade your ship, and try to get by.

Moment-to-moment, it's mostly hiding/EMCON, reading instruments, making sense of sensor blips, plotting routes, managing heat, and trying not to get killed by a single missile that slipped through the PDCs, or a railgun shot through the reactor.

No sectors or jump gates — even at 2g constant acceleration you get around quite quickly. After all, space is mostly... *empty spaces* :)

Some of you might remember my [previous posts](https://www.reddit.com/r/spacesimgames/comments/1p3z67a/empty_spaces_expanse_x4_and_nebulousinspired_2d/) with a similar concept. The last attempt fizzled out around 4 months ago due to a lack of direction, a messy browser-based codebase, and simply the resulting gameplay not being any fun.

This time I decided to take it a step further. If I can't make a realistic space sim fun due to it being too complex, I'm going to try to make it fun *because* it's too complex :)
