If I could impart any wisdom, it would be the following
- Do not count your chickens before they hatch... err.. something like that. In other words, don't get caught up worrying about a million different games you want at the same time, focus on certain titles. Know the games you want, not just the name, but why you want them. Research the kind of games you're into and for what platforms. Which leads me to my second point...
- Don't go all willy buying everything you come across, try to stick to making informed choices. While quantity can be impressive, quality is more so. Try to refrain from impulses, unless you've got a really good feeling about the content or the value of what you have found. Game hunting is a great idea of just starting out, but waiting 6 months and some change to find a game you'd like to have for $3.50, instead of shelling the $25 to go ahead and get is a very small victory in the grand scheme.
- I wouldn't recommend going for any complete collections unless you've got lots of money, lots of time, and live in a densely populated area. While it's just my opinion, completionists end up spending a lot of time and money buying lots of junky stuff out of necessity. There's more junk out there, than there is good stuff.
- If you find games that appear to be boxed or cased, always check that it's actually inside, and if it's a disc check the condition. The one time you take this for granted, it will bite you.
- The time to buy something rare is when you see it (in the wild). Otherwise, you'll regret it.
- If you're going to flea markets, get up no later than 5:30 AM and go, take a flash light if you need one. Be there as people selling arrive and set up, and no later.
- If you're into collecting modern on the cheap, don't discount GS as some evil empire because they offered you $4.83 for that game you brought in that one time. They're everywhere and their used games are heavily discounted. 2,500 games under $20, as they say.
... and that's all she wrote.
