14 DAY TRIAL // I know many of you are not old enough to get a credit card, so you have to ask you older bother or sister, or one of your parents to give you their credit card number in order for you to pay for a Steam game. At least, that would have happened until Steam and PayPal joined forces.
As of November 22, Steam will offer support for PayPal, and you can use PayPal as an alternate payment method. You can use PayPal to get any Steam game you want including Dark Messiah of Might and Magic or Medieval II.
You can get Dark Messiah of Might and Magic for US$ 49.95 and Medieval II: Total War for the same amount. These are not the only games available on Steam, but there are many more such as RoboBlitz, The Civilization series, Psychonauts and Day of Defeat.
One particular offer caught my eye, namely the Valve Complete Pack, retailing for US$ 79.95. This pack is made up of: Counter Strike, and its other versions Condition Zero and Source; Day of Defeat, Deathmatch Classic; Half-Life, Half-Life 2 and its episodes Deathmatch, Episode One, Lost Coast, Blue Shift, and Half-Life Deathmatch: Source; and Opposing Force, Ricochet and Team Fortress Classic.
