How would you make money by buying and selling (and possibly trading) games?

Question

I love playing games and it would be great it I could make some money, too

Answer 1

It's called Gamestop and they make money because they buy games for less than they sell them.

Answer 2

Well you would try to buy video games that were pretty cheap and then sell them for even just $10 more. Its a profit sort of thing. So if you bought a video game for $50 you would have to sell them at $60 five more times to make the breaking even and then another one for profit.
