Sorry about the silly meme in the topic title. Anyway, I think that food buffs should stack for several reasons.
1.) It would boost the economy because people would consider buying all the food types.
Nobody buys anything except Teaching Pies and Persisting Pies. The atmospheric protection foods are basically useless. Think about it: the only time you would use atmospheric protection foods is to gain access to high tier planets. However, those same planets require the use of expensive gear and most people seem to prefer using a Persisting Pie to get the most out of those tools. And so people tend to invest the skill points into atmosphere protection instead of buying the atmosphere protection foods. If it were possible to super-buff yourself, then I think that more people would consider buying a whole suite of foods before going on their adventures on high-tier planets.
2.) The current system is counter-intuitive, especially with the Well Fed buff.
I have, on more than one occasion, accidentally blown away a Teaching Pie buff by eating an Earthyam Stew. Wanting to keep my character Well Fed seems like such a natural thing to do. I don’t want to be constantly nibbling on Cooked Earthyams like some kind of peasant. Eating a quick stew is almost automatic because I want to prevent my character from getting tired so easily. But you have to be very careful not to do this if you’ve decided to use another buff. Furthermore, it seems really weird that a luxury food like a Teaching Pie would be less effective at keeping my character Well Fed than a cheap Earthyam Stew.
3.) It could reduce the reliance on alt characters.
I wish that I didn’t have to use an alt character. It doesn’t seem like the way the game was intended to be played. My main character is sort of an all-rounder, I think, with a bit of a bias towards mining and gathering. I haven’t thought too seriously about optimizing the skill points perfectly for some particular task. My character is not well suited to slaying wildlife on high-tier worlds. It would be great to be able to buff myself for a hunting adventure by eating Invigorating food, eating Energizing food, eating an appropriate Shielding food, and be able to keep myself Well Fed at the same time. (And, to reinforce my point 1 above: If this were an option, I think that people would buy a lot more foods, which would make it actually worth having a seriously well-stocked food shop.)
Are there any reasons why food buffs shouldn’t stack?
