Endless Sky!

Star Sonata is a space-themed massively multiplayer online role-playing game (MMO), that uses a third-person 2d overhead view similar to that of Asteroids. In addition the game offers complex and involved commerce, construction and team systems. The goal for players in Star Sonata is to bring their team to domination and claim the seat of emperor.

The player starts as a freelance space pilot in a shuttlecraft, out to make a penny in the vast and unforgiving galaxy. There are many ways to play Nova; for example, a starting player seeking funds can become a trader or courier, delivering cargo between worlds; become a pirate or bounty hunter, attacking and disabling ships to steal their money, cargo, or the ships themselves; become involved in one of the main storylines; or even conquer the galaxy by subjugating worlds.

Naev is a 2D space trading and combat game, in a similar vein to Escape Velocity. Naev is played from a top-down perspective, featuring fast-paced combat, many ships, a large variety of equipment and a large galaxy to explore. The game is highly open-ended, letting you proceed at your own pace.

You're too busy crafting the perfect vessel, a spaceship pristine and precise and, perhaps, powerful, agile, and envy-inducing. Your shapes and colors will induce both fear and wonder into the electronic hearts of whatever insectoid, angley, squarish, plantlike race of alien ships that you come across in your digital safari.

A 2D space exploration, combat and trading game of epic proportions!
