How popular are the one day sales this week on Steam? Well, one of the five games on sale on Monday, Prey, actually ran out of CD Keys (BioShock priced at $4.99 was put in its place). Today there are some more games cut down to the bone (in terms of their price) for the next 23 hours.

Like yesterday's this this new list has all but one of the games on sale for less than $10 each. The exception is King Arthur. The recently released RTS-RPG is on sale for $19.99 today. The other games are Silent Hill: The Homecoming for $9.99, Stormrise and Company of Heroes: Tales of Valor for $7.49 each, Jade Empire for $3.75 and Mr. Robot for a mere $1.99.
