Like cars, it's used the moment it comes off the lot. In this case, once it has holes in it, it's used. Period. Drill it, put it back in the box and sell it. It's used.
But like cars, there's a difference between a 1 year old used car with 10K miles and a 5 year old used car with 50K miles. And just like cars, some are still going strong at 100 games (50K miles) while others are basically dead at that point. I won't pay the same for a used Magic at 100 games compared to a used Counter Strike at 100 games. The Magic is basically middle aged or older. The Counter Strike is just getting broken in, even if their original prices were similar.
