I'm always worried that something I am mildly interested in will become lost in reseller hell, as you put it. Bayonetta 2 and the first Xenoblade Chronicles, for instance - I regretted not buying those when they were first available. But honestly, would I have preordered them back in the day, considering that I don't have a Wii or Wii U? Probably not, especially since they were standard editions.
Which puts me in a predicament, of course. If I'm interested in a game, I'll preorder it if it has a CE. If not, I let it go and wait 'till it gets cheaper. Unfortunately, with games like Bayonetta and Xenoblade, it never really gets cheaper and ends up out of print.
I guess these are just my issues with collecting anyway. I hate that I throw so much at games that I will end up not playing for a few years, if ever, and I'm glad if the game does end up being hard to find later, but it is a little annoying to see the same item still available years later for half off (though this is good in case my copy ever goes missing).
Now that the boyfriend preorders a lot of my items for me, it's even harder for me to keep track of what I have preordered. I'm thinking I'll be doing some cleaning this weekend and really get a sense of what my game collection looks like these days...
