Valve Shuts Down Fan-Made Team Fortress and Portal Projects

Valve has taken action against fan projects including Team Fortress: Source 2 and Portal 64, issuing a DMCA takedown against the former and indirectly causing the removal of the latter due to its reliance on Nintendo's proprietary libraries. This move has surprised the gaming community, as Valve has historically been supportive of fan projects. The unique circumstances of these cases, involving unauthorized use of Valve assets and reliance on Nintendo's proprietary tools, may have prompted these actions, signaling a potential shift in Valve's approach to fan projects.
