Valve's 19-Year-Old Portal Franchise Still Moves Limited-Edition Hardware in 2026

Dbrand's Companion Cube case for the Steam Machine, shipping with an exclusive Test Chamber Steam Controller skin, reflects the durability of Valve's mid-2000s cultural output. Portal, which launched in 2007, has not received a mainline sequel since Portal 2 in 2011. That a third-party accessories maker confidently bets on 19-year-old puzzle-game imagery to drive sales reveals how tenaciously gaming IP from that era retains market pull—a gravity most publishers would envy.
