It's like Netflix, you get out of it what you put into it. Maybe take the free trial and play the games the way that you normally will play them. Then calculate the cost of each game based on how many you played and how much you paid.
If the cost per game is more than you'd spend at a local video store, maybe not the best route to go. Of course, factor in that the video store may not have what you want.
Also depends on the type of gaming you like to do. If you like to just blow through games and rarely replay them, then you'd likely like it. Personally, I replay the majority of my games at least once, and I tend to take a longer amount of time to finish them, so paying for gamefly wouldn't make sense for me.
. Anyway, does anyone here have Gamefly? Is it worth it if you do? Thanks for any suggestions!
