The Benefits of Playing Free Games

Games like diablo three have a market place where you can buy and sell items that you've grinded for in the game. That's proven to be a huge money maker, i think, from articles i've read. And so they most likely, when diablo four comes out, they won't even charge for it, because they'll just have this market place mechanic. So a lot of aps are going to the premium model. It has obvious benefits, right? Because it completely removes the barrier of entry.
