I think that this is the worst generation for consoles in terms of longevity of games- Sony and Microsoft need to work HARD to sell their consoles, and lowering game prices is a good way to move units. Sure, the systems sell fine, but new games come out so frequently now that the average gamer isn't going to drop $66 (with tax) a couple times a month. So after a game is out for a bit and the numbers can't compete with the next big AAA title, they drop it $20 for a "sale" that just happens to be every other week - I'm looking at you, Advanced Warefare. Some titles go even cheaper. I remember Sunset Overdrive was $35 at Best Buy back in October, only a month after it came out. And even when released, Killzone never stayed at $60, it was $49.99 within 2 months of console launch and has been a $30 title ever since. Knack is $20. Why? Cause nobody wants them anymore.
