I have just started using Gametap and at first I rather liked the idea. I have been using a free pack to see if it was worth paying for, and yes i would pay for premium. However, to entice people into paying, put some "good" games onto the free pack. I was playing O.R.B for a while before it was taken off the free games list. Not only had O.R.B been taken off but several other games. You can't just take a game off without replacing it or warning the user first. I believe if you are going to make a game free then keep it free, besides most of the games are pretty old (no offense I like old games).
