Space based, semi-Newtonian physics MMORPG. Free 8 hour trial spread across as much time as you like, no cc required. After that subs run for between $7-$10 a month.

Some good features:

*open PvP: you can be killed anytime, anywhere, however death is relatively painless and some areas are heavily guarded

*huge backstory: spans over 2000 years, includes detailed history on each of the three nations, and a unique writing system with original pictographic and phonetic alphabet

*twitch combat: you, the player, are in direct control of your ship.

*player involvement: design your own missions for the game, create or help run an event attended by other players, or join one of VO's many guilds

*multi-platform support: it's available on Linux, Mac, Windows, and Android phones and tablets

*great dev team: supported and developed by a small indie dev team that are highly communicative and dedicated to their work and vision

Come try it out if you get the opportunity. I've been playing since June 2003, and have continued to enjoy the experience as I've watched the game grow and evolve since then.
