Poll: Selling your games to buy them on a different console? What was he thinking?!

[Logan Badass]

So a little backstory is in order here. Before the current-gen consoles came out, a friend of mine was a big sony fan. He still is, but when the 360 came out, he got one and played it, met me on Xbox live and enjoyed the console seemingly very much. He got tons of games for it, some multi-platform and some exclusives. Even after he got a Playstation 3, he still liked to play his 360. That is, until about a month ago, when he decided to sell all of his 360 games and buy them again (full price) for his playstation. At first I was a little surprised as it seemed that with the money he made from selling the games (he gave the 360 away) he still would have lost money to get them for the ps3. So my question is, what could he possibly achieve by doing this? Other than just having them on a different console. If he had the games already and most of his friends have Xbox's, why sell them. To prove he was a hardcore sony fanboy? wtf. I just don't get it. I still play with him on PSN, so it's not a big deal, other than that I'm called an *F word* when I get a game on the 360. I'm just a little put off by his wacked logic.
