[RPG] Who took the Star Wars RPG license over from WotC in 2011

The Wikipedia article has a lot of detail on this subject, but here are some of the highlights (cribbed directly from the article):

• Standard hit points have replaced the former Wounds/Vitality system. Characters also have a Condition Track which measures how much they are currently impaired.
• The number of character classes have been reduced to five — Jedi, Noble, Scoundrel, Scout and Soldier. Each class progresses along "character trees" similar to the d20 Modern system. Prestige Classes are still available, but they each also have one or more talent trees.
• Virtually all attacks and offensive powers now require a roll against one of three defenses — Reflex Defense, Fortitude Defense, or Will Defense.
• Skill points have been eliminated. Characters have a number of "trained" skills they can pick based on their class and Intelligence bonus. Some skills have been combined, integrated, or simplified.
• Force sensitive characters now have a single "Use the Force" skill. Force users can also select Talents related to the Force, and prestige classes grant Force Techniques and Force Secrets which further improve their ability to use the Force.
• The game includes an optional Destiny system. Characters receive "Destiny Points" which are more powerful than Force Points.
• Multiple per-turn attacks are weaker and now require feats to attain.
• Rules and stats for NPCs have been streamlined. There is only one non-heroic class for NPC characters. Non-sentient creatures in the game use the "Beast" class.
• Alien races and classes now rarely grant bonuses to skill checks; instead they often allow a reroll of the check under particular circumstances.

The Rules Upgrade (transcribed from Star Wars Adventure Journal, issue 11) that WEG released would probably have the most complete listing of what actually changed. The blurb at the top states:

Aside from the extensive physical makeover of the book, as well as the inclusion of a much needed index, there were only a few changes to the game system.

With which I am inclined to agree. The actual differences are small, mostly clarifications and errata.

I personally prefer the R&E over 2ed because of the additional clarifications. I wouldn't try to use them together, as they are not strictly 'compatible' ( less so than D&D 3e to 3.5, which is comparatively a much larger revision ) because most things that are changed are changed in small or subtle ways. As for using other 2ed source books, i.e. not the core book, I have yet to run into any problems with it, though I tweaked a couple of the powers to bring them more in line with the others.
