This looks to me to be artwork that you would see on the side of a 12 bottle box of whiskey. My guess is this will be used on the various pallets stacked with boxes for decorative purposes.
To be exact, you didn't buy a console game from TFP in the first place, so you are correct - you definitely won't buy a console game from them again. Unless they release two more, in which case you might do.
I'm not sure that passive healing uses food. I was always under the impression that it was stamina restoration that was linked to food consumption and if you've focussed entirely on Fortitude then you probably haven't got any points in Sex Rex.
Also, if you're going in jabbing and power hitting occasionally you will be using a fair amount of stamina, could this be the reason you're using a lot of food rather than the healing?
