I have played about 20+ MMORPGs including WoW etc. ....so virtually played them all,I can honestly say I had the MOST fun in SWG PreCU,the player base was decent and social aspects great,taking down a Kryt was fun back in those days with 12 player grouped teams and you had so much to do,social player towns and guilds were excellent.
Making money was not that hard either get a group together and each grab 2 missions from the mission terminals, go and out and kill the mobs so by the time your group had finished you was up 100,000 credits.
Crafting was probably one of the strongest aspects of SWG,it felt like a MMORPG with live players, as a jedi you never knew when a player Bounty hunter would appear for PvP battle to kill you,I enjoyed Master Doc the most and yes I got 6 classes to master level.
How many SWG players had there swoop bikes destroyed by a Kryt lol.. I know too many including myself did( don't leave your swoop out lol..)
After PreCU they went carebear approach dumbing it down so anybody could be Jedi and making mobs a lot easier to kill ,crafting wear and tear went way of Dodo,they copied a few things from WoW as well rather then keep SWG unique,this was the start of the end for SWG.
I forgot the mean Nightsisters with their NPC force powers,took two of us "buffed up" to kill one in PreCU days (they actually scared me when I went solo exploring on dath lol).
Each server had famous crafters back in those days where you could buy high quality gear,plenty of player shops for virtually anything like ship parts,housing ,armour,weapons,swoops to name a few.
It had some unique instances to ie like "The Warren" before they dumbed them all down after PreCu.
You could go PvP when you like ie join empire or rebel faction side and work your way up in rank too , attack enemy PvP players or go and grab some faction missions attack enemy towns including NPCs like stormtroopers etc...
SWG you could go and explore any planet,go in space and explore ,it was like a virtual live world.
Nowdays everything is so dumbed down even ToR has carebear approach.
I'll say no MMORPG is bug free and that includes ToR or any MMORPG you can meantion,I found about 10 obvious bugs myself without even trying to bug test in ToR and I can guarantee you there will still be bugs when it goes live,its a MMORPG which means there will be bugs.
End of the day we all have our favourite MMORPG but to this date I have not played any MMORPG as good as SWG PreCu,I miss those days.
