Had a dream that Valve changed how items worked in Team Fortress 2 with the only reasoning given being that this involved "pending legal issues, which we do not discuss as a matter of company policy."
The specific changes were as follows:
Weapon drops, and everything created from them, are now untradable.
Items purchased from the store are now untradable for one month after purchase.
Keys have been removed from the store. All new crates can be opened by paying $2.50. All old crates have been removed from their user's inventories.
Specific crafting recipes for weapons have been removed (this was given the explanation that they were "too confusing.") Now to craft weapons you either need to use the class token/slot token recipe, or use a new recipe where you craft six weapons together to get a random weapon.
