1. I would do more to consolidate the Technical skills. There are a LOT of them, and they are often redundant. This goes double when you start adding in skills from some of the sourcebooks like (A) Space Station Engineering, (A) Capitol Ship Engineering, Mechanical Repair (from Shadows of the Empire Sourcebook, an NPC repairman on Coruscant had it, meant to represent ability to repair plumbing and other mundane utility/hardware issues).
Solution 1: Go back to the (fewer) mechanical skills in 1st edition.
Solution 2: Combine away. I don't think the game would suffer.
Solution 3: I suggest upthread a bit to allow a lot of overlap with the skills. If a character is trying to hide some data in a computer bank for his Rebel contact to find, and this character has a high Droid Programming skill, then allow the character to use that at a -1D penalty rather than standard Computer skill.
2. I would come up with a better way of handling wounds/damage. As-is, a starting wookiee with a starting strength of 6D has little to fear from a random 4D blaster pistol hit. If he's wearing any armor, he can basically shrug off anything except sustained fire and becomes a juggernaut.
1. In WEG's
D6 Space game (free, see the link earlier in the thread to obtain it), a second method of handling wounds is offered.
2. Don't forget that, the more D6 you throw, the more centralized the distribution. More dice means highs and lows will on occur as often. The average on 4D is 14. The average on 6D is 21. BUT, you'll have bigger swings more often with the 4D throw. The spread can account for a Wookiee's toughness and ability to shrug off wounds.
3. Limit STR for rolling wounds. Use the same rules, but half STR. Or, apply wound effects and other penalities that do not normally apply. For example, a wookiee with 6D STR is -1D to all skill checks, but not the damage resistance roll, when wounded. Well, consider that a wounded wookiee cannot resist damage as well as a wookiee that is fully healed, and thus use the -1D penalty.
3. I would genuinely love a well made sourcebook that incorporated events after WEG collapsed in '98.
See the link up-thread for the fan made Clone Wars sourcebook. It will blow your mind. It looks just like a WEG product.
