Good for a few hours, but will ultimately leave you disappointed, angry or worse.
Gone are the many professions that made customization and having a niche in an online world. The sophisticated profession tree that allowed people to be chefs, armor smiths, swordsmen, doctors and rangers is replaced with fewer "key" professions seen in the movies like "trader", "spy", and "smuggler". Instead of learning skill boxes in each profession, the system for "gaining" levels is controlled by a track from 1-90 that assigns new skills and abilities about every fourth level-up. There is no longer any customization or dabbling in other professions.
Gone is the traditional turn-based combat resolution. Now, the player must click furiously to activate their attacks against enemies. After playing for about 8 hours or so, I'm still not entirely sure what effects the different attacks have. I cannot figure out how to display the combat information in my chat window. The official SWG site and the in game "holocron" are not very helpful.
Gone is the tricky path to Jedi. Replaced with the profession "Jedi". This seems to be one of the most criticized aspects from veterans of SWG that had to "grind" to unlock Jedi slots or do the new quest system. The Jedi profession doesn't seem to be that great overall when I played at CL69.
Essentially, the fun parts of SWG that made it innovative are now gone. Instead of playing a distinct character who lived in an online world community, one now plays as a mere copy of almost every other player in a world that no longer needs any interaction with other players.
Overall, Sony has made a decent game for the first 30 character levels, unfortunately, that leaves 60 more levels essentially broken and not very fun to play. Moreover, the essential problems of the original design flaws remain. If someone decides to create a new SWG in the future, don't include Jedi if you want the time period to be between Episodes 4 and 5. First, in the Star Wars chronology Jedi were rare and in hiding, not running around in droves. Second, from a gameplay perspective, there are too many games that execute the Jedi experience exceptionally well (Dark Forces II and KOTOR series).
Let players truly be citizens of an online Star Wars universe. Let us be smugglers, gamblers, bounty hunters, chefs, businessmen, dancers, and politicians. The NGE has a creative vision that is focused on quick button mashing and a "hero role" for every player. The best times I had in SWG were as a lowly marksman, grouped with twenty friends trying to take down creatures in the wasteland outside Anchorhead. Yes, there were bugs, and yes, we got frustrated and angry, but we had fun. Now those days are a long time ago and far far away.
