The boulder is easily 8-10m across that puts its weight around 1500-3000 metric tons ( ~ 2600 kg/m³ for typical Himalayan rock density)
to move such a massive object the estimated drag force on that boulder could easily be of the order of 5 million to 20 million newtons
for comparison, Falcon Heavy first stage rocket produces a force of 23 Million newtons!!!
26 years ago today, Age of Empires II: The Conquerors arrived on PC.
Back when an expansion pack could feel like an entirely new game. Big PC box, CRT monitor, hours disappearing before you even realized it.
Still one of the best eras of PC gaming.
