This covers mostly the pay-for-gems model of scamming, which is certainly a big part of the problem. Another problem is that it is hard to find "complete" games now. Years ago, you could play a game for literally 200 hours and still not see everything. Now, for the same price, you get what feels like about 40% of a real game, and a series of ten-dollar "downloadable contents" fill in the rest of the game that you should have had.
