Their sales definitely had something to do with this as well. Before these kinds of sales, PC games were fixed at a certain price point and would take a long time to see a price drop. Now, I'll see fairly new games that may be marked down anywhere from 10% to 25% and, at least for me, I feel much more inclined to purchase it if I like it.

Granted I have a backlog of games to get through, but still it made purchasing games much more approachable as I know I won't be breaking my wallet over one game.
