Most Xbox Live
gamers are used to the normal Microsoft ways when it comes to their Live games. You pay a certain amount of MSP (dollars) for the game, then have the opportunity to purchase extra content that comes along with any Live game. Outside the 360, free-to-play gaming has hit the ground running, and while Microsoft has yet to confirm this, there is a possibility that free-to-play will be coming to Xbox Live.
IGN reported on their site that a trusted source had told them that [Microsoft] will allow publishers and developers to release games through the service for free where users can then purchase additional content, such as weapons, experience points, in-game currency, and perks. We will most likely not see free-to-play anytime soon, but when (and if) we see it, it will bring enormous changes, and hopefully for the better.
