One major reveal that occurred at this year's Penny Arcade Expo was the confirmation of another planet to be featured in Star Wars: The Old Republic, and not just any planet, either! The heart of the galaxy, Coruscant, will be playable in Star Wars: The Old Republic.
What's the big deal about Coruscant? Producing a planet like Coruscant in an MMOG would possibly be one of the more challenging things you could do. So as a Star Wars nerd, BioWare is really outdoing themselves yet again by promising to feature Coruscant in Star Wars: The Old Republic.
You can't simply lay down some terrain, pepper it with structures and call it a day. Coruscant as a planet is almost entirely covered in cities. Imagine New York City, only planetwide. There are no bodies of water, and the only landmass that really remains would be the Manarai Mountains. If nothing else, experiencing Coruscant fully realized in an MMOG is enough reason to be excited about Star Wars: The Old Republic.
A new trailer featuring the planet was demo'd at the show, and GameSpot has a high resolution version of it up right now. Check out the high-res trailer here.
