After planning my first LAN party in over a year, I discovered that the game I planned to play, Battlefield: Bad Company 2, intentionally does not include support for LAN-only servers. In over 15 years of hosting LAN parties, I have never encountered a game that does this.
EA made this choice, supposedtly, to curb piracy. What they have done is guarantee that I will never buy one of their products again. Ever.
Strong work.
