Why aren't we still kids? (for the veterans). But if you're a newer, younger forum member, you're welcome to respond to this thread, too - as your enthusiasm for Star Wars will be appreciated for reminding so many of the older forum members here how we used to be - and even could be again.
So if this does NOT sound like you - tell us anyway!
If your enthusiasm has mellowed, I thought about some reasons as to why:
1. Space to put all this stuff - my biggest concern is running out of room.
1a. Living with others and space limitations (Well, I'm not married, don't want to permanently live with a girl (what's wrong with having lots of girlfriends over the years and no wife?), and I won't have children and risk passing my kidney disease on - plus I don't want kids and prefer peace and quiet, and freedom from responsibility). If you do not use birth control yourself (don't trust a girl to) you may find yourself no longer able to make your own lifestyle choices.
2. Finances - well, earn more money so you don't have to make choices on what you purchase based on disposable income (if you can avoid this in the current rough economy). You still might be challenged by No. 1 above (space to put the stuff) but if it comes down to alternative choices for entertainment (for example, I love baseball games and rock concerts), getting more cash could give you more options. If this is way too hard to accomplish right now because of being laid off, having pay or hours cut, and similar reasons, might you go back to collecting more when you see your income eventually increase (or bills and debt get all paid off)?
3. Time - If you must work more to get more cash, this can happen: you won't have time to enjoy the alternatives such as baseball games and rock concerts and the 1/2 hour or hour you spend toy hunting becomes your only, totally arbitrary activity you have time to do, thereby decreasing its pleasure value because you don't have time to make any other choice (but to toy hunt from 8-9am before work, for example). I'd recommend saving for a non-working vacation before toy expenditures. You might not travel anywhere, but instead take time off work and just spend it and the extra money on completely self-entertaining things other than Star Wars. Then when you go back to Star Wars, it will feel as though you haven't missed out on anything else. If you got to take a luxury vacation (and could afford it) would you go back to collecting when you returned?
4. Completism - I never understood this. I decided I wanted to buy SW stuff to build dioramas - and sort of artistically express myself with the wars I set up. Therefore, I skip figures I have no interest in, or re-carded ones, etc. Though I may have to army-build certain other figures. But because of reason No. 1 above (space to put your stuff), you have to define limitations. That RC Hailfire Droid looks fun, but though I want to play with one, I have no place to keep it, nor any "need" for it. (I have an extra hailfire droid still in its box as it is - the TRU exclusive one that I got for a gift and decided to raid for the General Grievous figure it came with, which I found useful to fight Nahdar Vebb and Kit Fisto when I got them).
But if you were going to start all over with the vintage-style cardbacks, it's really tough to say if you'll be satisfied. Ephant Mon is probably never going to be carded on a vintage-back and he is still (IMO) probably the greatest SW figure Hasbro has ever produced for the modern collection (2002). Everyone has their own favorite though, and I couldn't tell you if it will ever be on a vintage card or not. (I think Hasbro, well aware of how popular the vintage style cardbacks would be for even prequel figures) saved this idea to drag it out exactly when the economy would be struggling. Financial reports suggest Hasbro is actually profitting and Star Wars sales are very strong right now and even gaining!)
So how do you feel about the state of Star Wars now, in 2010, and your involvement level with it?
