Valve is making some changes to written store page descriptions on Steam.
Starting in “early” September, the Steam team (the dream team’s lesser known cousin) will be “enforcing new rules for what can and cannot be included in your written store page descriptions”.
These changes are coming into force due to a recent “trend”, as Valve describes it, that has seen a number of developers using their store page descriptions as a platform to “present information or links” to other places.
