When do you buy a game that could be a future collectible?
As a result of knowing what I want, I've been keeping my eyes peeled for some good deals if that means picking up things before I buy a system. Part of my question surrounds my love for some of the big series (Mario, Zelda, Metroid, Castlevania, and various RPGs). Often times these games, especially Nintendo, seem to come down to a mid-range price and disappear to then become "collectible" status where you're paying new or higher prices for a used game.
When do you pull the trigger and buy some of these games? Typically I buy my games around the $10 mark. Whether that's from Craigslist, Gamefly, or Ebay, I rarely spend more than $20 unless it's a game I really want new. As a result of my hesitation to purchase these games, I am currently Zelda-less for my 3DS. I am wondering if this will happen with Xenoblade Chronicles X?
