When Mortal Kombat releases on April 19, it will include an online pass code that unlocks the online multiplayer features. This has been done before, and we expect we'll continue to see this trend grow more and more. Before anyone gets their panties in a bunch over this, take a deep breath and think about it: Game developers spend years creating these games, and they lose a sizeable chunk of their money from the used games sales. It’s only logical for them to try and make some profit on those after-market sales. If you do get your game on the cheap a few months down the line, you can buy the online pass for 800 Microsoft points and $9.99 on the PlayStation Network. THEY'RE JUST TRYING TO FEED THEIR FAMILIES, PEOPLE. [via Joystiq]
