I see the steam summer sale has had all the assassins creed games, except for black flag, at around 5 bucks and have been very tempted to buy them. PC is the best at running these games anyway, but I already own the Ezio trilogy and III for PS3, which is arguably the worst platform for the series(except for revelations and maybe III). I'm mulling over double dipping and trying to trade in my PS3 copies for a few bucks, but what do you think? Have you ever double dipped from console to PC? Vice-Versa? Different consoles? Even the same game twice for one console?
