More and more game companies are finding that a microtransaction
system that is implemented in your game will rake in a lot of cash.
But is it good for every game out there? Some games that have seen
huge success from the microtransaction system has been "Team Fortress
2", "League of Legends", and many more. For those who don't know what
microtransaction are, they times that you can buy in the game for real
money, or you buy special in game money with real money to buy these
items. Usually these items are just for show, but you can sometimes
unlock items ahead of time, or buy boosts so you level up faster.

Now more companies and games are trying to implementing
microtransaction with their games, but why? Is it to just get some
extra money out of their customers? Or maybe they have some other
ideas that they want implement. Over all, I really don't think every
single game should have microtransaction. Why should every game that
you play be a dress up game for your character?
