The game switchover thing did not really resonate with me at the time of the tour.
But you can imagine that to an operator this could be hugely appealing when rotating titles to maintain the cash drop in different venues. 5 mins to swap over a game (tranny, side panels, playfield with three connectors, software). And without the hassle of dismantling, lugging it about, tail lift tranny van, damage to game/ venue/ man's back ....
