Listen up, budding HanSolo892s! LucasArts is offering everyone the chance to try out Star Wars Galaxies and its Jump To Lightspeed expansion pack for 14 days.
The "enhanced trial" version offers all the content from both, and if you're still enjoying it once the 14 days are up you can pay to continue playing without having to download anything extra.
You might want to though, because anybody who converts to a paid-for account will receive a free copy of the Rage of the Wookiees expansion pack via download, along with an exclusive in-game item.
