Game collecting today is hard and expensive unlike in the 90's when it used to be easy. Since no one really knew the potential value of games, there were many titles you could pick-up at remarkably low prices. As time went on and people started realizing the value of rare games, prices went up.
I found myself cringing at the lost of Harvest Moon for SNES, which now goes for roughly $300 with the case. Many, like myself, traded games in at the local video stores for new ones. I know I was tempted to sell and trade in my games, instead off keeping them around to see if the appreciated in value (which many of them did).
But even before you start thinking about prices on things, the bigger question is what should you collect and what is really worth buying back? USGamer is here with a list of Game Boy Advance games that are actually worth the acquisition.
Imagine creating an awesome game that plays like a mix of Shinobi and Bionic Commando. Imagine pouring your heart into it, handing it over to the publisher, and having them slap the name Ninja Five-O on the cover. How would you feel? Hudson Soft created this underrated gem for Game Boy Advance, placing players in the shoes of ninja cop Joe Osugi in his fight against ninja terrorists. Everyone missed Ninja Five-O, partially because it had no marketing and partially because of a cover that said "cash grab".
Current Price: $350
Since no one bought it then, Ninja Five-O is a hard game to find now. Good luck.
Final Fantasy VI Advance
One of the finest Final Fantasy games on Super Nintendo, re-released on Game Boy Advance. The game was already nearly perfect, but this version adds a new translation, better graphics, two new dungeons, and four new Espers to play with. If you're really serious about collecting Game Boy Advance games, don't think about it, just buy it.

Current Price: $20-60
This is another game that was a tough sell when it came out, but with distance it becomes a good purchase. Pokemon Emerald is the "Director's Cut" version of Pokemon Ruby/Sapphire and came out two years after those original releases. You get all the Pokemon from Ruby/Sapphire, a few more from Gold/Silver, and the Battle Frontier. It's the last feature which makes Pokemon Emerald a great purchase; Battle Frontier was trapped at the end of the game, but it provided a new challenge for veteran players.
Current Price: $20-30
It's a bit more expensive than Ruby/Sapphire, but it's worth it for what you get.
