Certainly, Star Wars travel is very much "speed of plot," but that doesn't lend itself well to making an RPG setting.
Given that we see the Rebels launch a few ships from their own bases basically into the Empire's lap, it appears that even long-distance travel can be accomplished in hours, provided you have clear lanes. Whereas when Luke, Leia, Lando, and Chewie were leaving the Cloud City, it seems that it takes days if not weeks to travel the murk of the more distant systems.

Certainly in the sequel movies, it seems to take only a few hours to muster a small vanguard of ships to delay the Empire.

It doesn't actually matter. The farther apart the habitable planets are the faster you make your drive. It's just that if you make them too close together somebody like me will know that's not possible.
As we're cribbing from Star Wars, we can let reality sleep.

I also did not account for the three dozen red dwarf and handful of detected brown dwarf stars - nor the two A-type stars (Sirius and Altair) in our neighborhood. And of those M-type red dwarfs, I would be very wary about putting inhabitable planets around any but the M0 to M2 types, even if they're in the habitable zone (see: Proxima Centauri and TRAPPIST-1).

So yeah, there's a lot more stars, as the M types outnumber the combined K, G, F, and A types a minimum of three to one.

Honestly, Garden planets are likely quite common, as photosynthesis is probably inevitable in any system with K through F stars. I would not be surprised if the 10% of K through F stars have one or two (around 2.25% of stars). That would mean that there should be 45 Garden planets within 50 ly of Sol (including the Earth). The only reason we have not seen them yet is because we lack the technology to see low mass planets that orbit their stars at a reasonable distance unless they transit their star (which is unlikely).

Of course, Venus and Mars may have been Garden planets until a billion years ago, so you would probably find more former Garden planets than existing Garden planets, probably 20% of K through F stars have former Garden planets. Potential Garden planets, like Earth a billion years ago, are probably as common as former Garden planets with probably 20% of K through F stars having potential Garden planets. It is these two groups that will form most terraforming candidates (around 180 such planets within 50 ly of Earth, including Venus and Mars).

IIRC, the problem was that the writers didn't all talk to each other, and the West End Games writers didn't have enough communication with Lucasfilm, but the people who wrote the comics and novels published after the first edition of the Star Wars RPG came out sometimes read that, and some of the other writers read the works of the writers who read the RPG's sourcebooks, et cetra.

This is why many novels gave blasters a range of 30-35 meters, and hyperdrive classes had a larger number for slower drives - and some writers who tried to reverse that trend got yelled at by the fan base, particularly when the Falcon would always have a class 0.5 regardless of which camp the writers fell into.

Author: "A class 0.3 hyperdrive? That's almost as fast as the Falcon!"
Fan-Base: "No way! It's faster! How dare you?!"

So I'm changing some numbers around for speeds, dropping travel times a lot, but two more questions travel related:
1) How should I scale FTL engine cost? If a more powerful Hyperdrive can get you to your destination 9 times faster, should it be 9 times more expensive?

2) I'm going to have hypergates scattered around the place that allow for even faster travel then normal, anyone got any ideas just how rare they should be? Out of the roughly 100 known worlds in the local cluster how many should have them?

Star Wars FTL should probably have a velocity of (1,000,000/[Hyperspace Factor])c through charted hyperspace channels and (1,000/[Hyperspace Factor])c outside of charted hyperspace channels. For example, the Millennium Falcon possesses a Hyperspace Factor of 0.5, making her one of the fastest ships in the galaxy, as she can move at 2 million c through charted channels and 2000 c outside if charted channels.

The importance of the hypergate depends on where it goes. If it accesses a star system outside of any hyperspace channels, it is not that impressive unless there are a lot of unusual artifacts (like a Ringworld). If it accesses a hyperspace stream unconnected to the hyperspace stream of the Old Republic, then it would be one of the most important installations in the galaxy. I would suggest only one though, as they are supposed to be really rare.

Depends on the paradigm you're going for, but given there is no increase in weight, I'd be inclined to scale the cost by the square of the speed - a hyperdrive that's 9x the speed but the same weight would be 81x the cost. If it's also 9x the weight, then 9x the cost is probably fair.

I'm not going an entire galaxy, if for no other reason then it's too much work. Also this idea started worming it's way through my head because of the way the SW universe is set up, it's set up for Game of Thrones tier characters, not smaller scale stuff

Not using channels, hyperspace it a go faster space, and gates allow you to go faster then your ship normally could, and even allow ships without hyperdrive to enter hyperspace, gate is only need at departure point.

Currently Class 1, 2, and 3 the same size, with Classes 4 and 5 are three times the size, but I'm thinking of changing it to be all the same size

So I've reached some other decisions: Every Half-G of Reactionless Acceleration gives 1/8 of one percent of C in top speed, but there's a minimum of 0.5c and both reactionless engines and hyperdrives are in somewhat limited supply, so most merchant men use a dean drive and a low spec hyperdrive, normally a Class 3, and supplement it with a reaction engine if they need more speed.

For a large extent Star Wars sits at TL10/(6+4)^ with "Blasters" possibly being TL(6+5)^

IMHO this is a sever low balling. Remember the Old Republic/Galactic Republic existed for 5,000 years minimum. With FTL it would be insanely easy to have the entire galaxy mapped out by time the events of a New Hope occur which the wookieepidia confirms.

The coverage of the Old Republic/Galactic Republic/Empire is very extensive. I would say 90% of all systems have been charted.
