I've fired up my 2014 Mac Book Pro with Iris graphics and tried out Blood Bowl 2 for some more 'on the go games'.
Things are fine in game at 1440x900 on low settings, no grass or spectators, but when in the menu systems or looking at Bob and Jim the laptop gets very hot with the fan maxing out. It seems the microphone animation and backdrop lighting may be the cause? This could maybe just be stopped if playing on low graphics?
