Star Wars RPG Saga Edition was released in 2007, and uses a heavily modified version of the d20 System. Sometimes called a “3.75″ system, it has many of the good features of both 3.5 and 4E D&D.
The Star Wars setting is obviously very well known, and translates quite well into an RPG. Anyone who enjoys the Star Wars movies will enjoy playing the roleplaying game, even without being a Star Wars nerd.
The Saga Edition has excellent class design and balance, such that Jedi do not dominate the game and all characters are useful. The rules are very strong, with combats resolving quickly but satisfyingly, and there are excellent rules for starship combat that are easy to get the hang of.
Because it’s based on the d20 System, Star Wars Saga Edition is very easy to pick up for those who have played D&D, especially if you have played both 3.5 and 4E.
Unfortunately, due to licensing issues, the books are now out of print, but you can still find them on Amazon and eBay. Ensure that you obtain the Saga Edition books, not the original d20 version.
