I loved low-level play in 4e. It was fun, and tactical, and reminded me of Saga Edition. In mid- to high-level play, it didn't match up to Saga in the least and I can understand why people got fed up with it. But then I tend to like quick combats, so if that's not what you're looking for then 4e is probably still a great game! Also Saga Edition for Star Wars play.
And fjw70 said it, you can be creative with any game system.
