Used games sales - good or bad for the industry, and do we care?

[theRepublic]

Whether or not used games are hurting the industry, a person should be allowed to buy and sell used games. Same goes for movies, books, and music.

The vast majority of used games are not traded in until the original new game purchaser has finished playing - more than two months after a new game is released - typically well beyond the window for a full retail priced new game sale.

I guess I'm not normal then. Most of the games I buy are quite old.  Just look at my most wanted.  A lot of older games in there.  Of the last three games I bought, one was released in '06, one in '07, and one in '08. I managed to buy those all new, by the way.
