We’re sort of becoming used to the microtransaction model for online games. Basically you can play a game for free, but at some point, you may have to buy bullets or buy more time. Something is limited to the point where you can stop playing for the day, or shell out money.

EA created free-to-play Battlefield Heroes with that idea in mind where players can play for free but have to invest in items such as virtual weapons or perks.

The community seems to be upset because there are changes to the cost of in-game items. The changes men that real-money cost of many items have been reduced but the number of Valor Points (in-game currency) has been increased. Increased by so much that as Ars Technica claims, playing your way to richness requires so much game time that it’s basically impossible.
