Star Wars holds up pretty well until about 12th level or so... at that point, they are the same level as most of the characters in the movies. My PCs would routinely use the plan, "Let's get captured, then escape" as their method of infiltrating absolutely anywhere. They literally let themselves get taken to prison, then assaulted the guards, took their weapons, hot wired the locks, infiltrated base security, grounded the ships in the space port, and defeated a couple of squads of stormtroopers, while effectiely jamming any transmissions from the base.
They also shot down a wing of 8th level TIE pilots in TIE-Ins while flying a shuttle craft, which had half the shields, hull rating, and armament of any one TIE fighter. Outnumbered 8:1, they destroyed all their attackers in, I believe, four rounds. Their pilot, a force adept/scout/noble, could automatically succeed at any piloting stunt described in the rules, including a full stop or wingover at any speed.
The soldier and fringer had so many attacks that they could count on rolling some 20s eventually, and would therefore try all kinds of shots, including shooting down TIE fighters with a tripod mounted blaster as they strafed.
That stuff you see in the movies? Anakin taming wild beasts while manacled, Han flying through asteroid fields, Kenobi defeating Grievous while hanging from a ledge? They were all amateurs.
I sent them up against three star destroyers without even worrying about how they would take them out. I just figured they would. They entered one of them in a stolen shuttle. They sabotaged the engines to self destrust, then took over the control room and opened fire on the other star destroyer. The third took heavy damage before escaping. They battled their way out, stole a TIE fighter, and escaped.
That's what Star Wars d20 looks like at level 12+. I wouldn't even let them near Darth Vader armed with any weapon of any kind.
