An Opinion on the Price of EP3

[whiteninja]

So, my older brother loaned me his EP3 game.... Then after playing for a while I asked if I could buy it off him. He hasn't played it in over a year (really!), and it's been played for less than 50 hours, and has the box and instructions. He was saying it was worth $25, I'm saying that it isn't as great as EP1&2 and is closer to $20. So what do you think? Am I being unreasonable? Is he?

Edit:..... I put a poll on here...... I apparently messed it up..... whoops......
