I hate you guys...
The fail of JTL was not because of JTL... they hired a new dev team to do JTL which made it work... took 4 years though before they added something to it though with an exception of ROTW which added combo missions with ground and space in one.
Anyhow SWG failed due to various reasons, mainly neglecting bug fixes and swapping those with revamps and combat upgrades = no additional content added to the game, they tried to add content with expansions and expansions only it does not really work that way, you need to add in content in between the expansions as well as well as keeping up the bug fixing.
Adventure planets they had Endor, Yavin and Dathomir, but the thing is that neither of the planets had any adventures bound to it other than heading somewhere and kill stuff basically, they could had been full of quests and adventures if they just did something about it as it is.
I really hope that SW:ToR would be SWG2 in many ways but also in its own unique way, as it is it is both Lucas Arts, Bioware and Electronic Arts behind it whom each got there niche of expertise in making games and the big plus to that is that they do not got a MMO to focus on now other than what they are building which means it would get all the attention,
Seriously hoping the full package with SW:ToR with both advanced space, advanced planet side stuff and many more features as well.
