I miss my houses. I miss decorating. The only time I felt disappointment so far was when I got my ship and realized I couldn't decorate it. I really hoped that SWG would become free to play, or cheaper per month, and I'd kept an account open there too.
But that has been it. I played SWG for 7+ years with 3 accounts, and had a blast. And I've loved SWTOR since the first day. I honestly don't think about the "end game" because I'm a slow leveler. I like the journey. And I am actually trying out every class, so it's been fun switching from one to another. I think I have 6 toons now doing different things, and still have more to try, so I think I'll be busy enough.
Games are always being enhanced. I love the game now, and suspect I'll love the new additions that are inevitable. By the time I get to level 50 they'll probably raise the cap, LOL.
So while I miss SWG, SWTOR has been an excellent next game for me and I look forward all day to playing that night.
