Simon Parkin in The New Yorker:
Finishing a single leg of the trip requires considerable stamina and concentration in the face of arch boredom: the vehicle constantly lists to the right, so players cannot take their hands off the virtual wheel; swerving from the road will cause the bus’s engine to stall, forcing the player to be towed back to the beginning. The game cannot be paused. The bus carries no virtual passengers to add human interest, and there is no traffic to negotiate. The only scenery is the odd sand-pocked rock or road sign. Players earn a single point for each eight-hour trip completed between the two cities, making a Desert Bus high score perhaps the most costly in gaming.
