"EA and BioWare are employing SecuROM for the PC release of Mass Effect, a copy protection scheme you may recall from its universally loathed inclusion in 2K's BioShock. The Mass Effect SecuROM annoyance factor may be much more extreme, as the game requires that the owner authenticate the copy every ten days, meaning that an internet connection is required to play the game from the get-go and until eternity. In other words, if you paid for your copy of Mass Effect, expect to remind EA's authentication servers every week and a half that you aren't stealing it."
For me, I have limited internet connection. I'm f***ing not doing this. I was already excited to buy this game, too. Just lost a sale, EA.
