paladin181: Do people really care that a game had a cheaper price at some point? "This game looks like a good value for me... but wait. It was available for sale for $1 less a few weeks ago. I won't pay this reasonable price for the product I want because it may (or may not) be sold for that lower price again!"
Lunacy at its finest.
We sure do care, and doing so is not 'lunacy' at all. On the contrary: it's the epitome of logic and rationality.
The lowest price at which a game has ever been sold is actually, usually, it's actual real true value, and also a price at which it will inevitably (at least 99%+ of the time) also be sold again in the (usually not-too-distant, i.e. within 3 - 6 months) future.
The makes the "lowest price in the last 30 days" an absolutely useless metric.
To buy a game at a higher price than it's actual lowest price ever is (usually) to be ripped off.
