True, although if you're in the EU, there should be a 30 days reference period.
"In all EU countries traders are obliged, when offering a discount, to indicate the lowest price applied to the item at least 30 days before the announcement of the price reduction."
Of course, enforcement of such rules is the problem here. But if you notice such discrepancies, you are more than encouraged to file a complaint to the shop and then to your national agency responsible for the protection of consumers if the seller doesn't act in good faith. I was fairly surprised to see how well the latter has worked against a large company in my Balkan country.
Regarding the Quake engine and its evolutions (Q3, Call of duty, RTC Wolfenstein), the most common trick was to modify the rendering mode of all player entities so that they are drawn above everything else.
The engine has a flag that is mainly used to draw the player's weapon (which is rendered above the rest). Using this flag for players was the "engine compliant" way of making a wall hack.
A bit off topic, but I have recently acquired a PCB which uses a Conexant CX92755. It is kind of supported by the Linux kernel, but I am completely unable to find a user manual / proper datasheet for this chip. If someone happens to have it stashed somewhere, I'd be super grateful as it would give me a few week ends of hacking with the board.
