Personally, the fee of the more popular MMOs has kept me away from those games, even though they are honestly my favorite genre. There are hundreds of dollars I could have spent playing games that languished in my bank account for lack of entertainment value.
I feel like the post-purchase "Fee v. Free" argument is missing a very important middle ground. Deciding whether a subscription is "worth it" works very well for the guys at either extreme; the avid gamer or those who have better things to do. But what about the undecided or casual player?
If I want to play, but I don't want to pay that much because I just don't have that much free time, I'll go find a free game or one with small fees for special items and services. They're all over the place, and if you don't play much, you're willing to sacrifice a little quality for the better price. You're...honestly not sacrificing much. A little lost in translation, maybe. And you don't spend enough time in the game for it to really matter, anyway. If the fee was a little lower, I might go for the better game. But it's not, so I'm not. On top of the price of the game, those fees would build up to astronomical sums as the months went on, but I wouldn't even notice because it would be within my monthly budget. I might even go for automatic payments if it were low enough, and if I didn't play for a month? "Oh, I forgot to cancel that. Nevermind, I'll find more time to play later."
Am I the only one who thinks this way, or is the game industry missing out by not having a lower fee for people who play a lot less?
