Open world style star wars universe
Begins Just as the order 66 is ordered.
You are a clone lieutenant and have the choice to kill your jedi or try to save them each leads to a completely different oppertunity. If continuing with your order you kill the jedi, and have the opportunity to stay and become a imperial officer. If attempt to rescue the jedi is chosen your men will turn on you and arrest you and still kill the jedi. Once youve been takin into custody you go to prison for the next two years. In the two yours the alternate pathway is the imperial career of a clone now either a storm trooper, an imperial officer, a bridge officer, or a pilot. After two years (of in game time) you come to the point where you can leave the military (recommended). Once this opportunity is taken then many opportunities will be available. You can become a bounty hunter planet hopping taking jobs from the likes of jabba the hut. To smuggling missions try your best to sneak that cargo past the impieral blockade. Or maybe just an explorer trying to see whats available in the galaxy. Who knows maybe even find your self some rebels starting a little aliance to bring a new wave of peace to the galaxy.
Now I know that this would be an enormous.
Also the size of the galaxy would most likely (hopefully) include the Star Wars Battlefront Galactic Conquest Galaxy.

Um... Ok.

You do realize you're barking up the wrong tree? If anybody gets the rights to a Star Wars game, it'll be Bioware. They have already released KOTOR and KOTOR II, and are currently running SWTOR.

Hi BiggG31 and welcome to the forums.

This won't happen. EA have a Star Wars games exclusive deal with Disney. Noone else will make any Star Wars games for at least another 8 years or so. And even then the deal might be extended. And Bethesda is probably very busy with the IPs they own already to spend efforts of yet another IP.

There was a simliar thread to this a few years ago too, if you want to read it.

It existed. It was an MMO Called Star Wars Galaxies. Sadly, the game no longer exists, but there is an emulator that is available if you can get your hands on a copy of the game disk (No steam Download!)
