It depends on the game. Video games definitely aren't the market you want to buy into if you're trying to make a profit though. Not many games increase in price and you can't really guarantee what games will be expensive over time.
I'm sure no one expected Dokapon Kingdom for the Wii to get as expensive as it did. The PS2 version was cheap all the way until a couple years ago and now it's also kind of expensive, probably thanks to the Wii version. The game looks stupid based on the cover but it's an excellent RPG party game.
