The loud, shouty parts of the hobby have changed - I took some time out and came back a few months ago and was shocked at the change. However, the friendly people are still friendly, Star Wars is still Star Wars and the toys are still the same (but with yellow bubbles
). You've got to try and ignore those would would treat this hobby the same as a share portfolio (you want to see some of the arguments on trading forums!), and try to enjoy it for what it is.
If you do decide to sell up (I cant judge as I did just that in 2010), then I will say that eventually you will more than likely come back (check out all of the old faces who have resurfaced this year). With that in mind, put your collection in boxes for a year and see what you think after that. If you don't think about it and your collection room becomes something else, then maybe it is time to sell. But don't be rash and sell now - you wont be able to buy it all back again, and the money gained is quickly spent.
