how many modules (average) is ideal for floor one?

[Klaus]

I feel like there isn't many doors so I try not to make past 3. your thoughts?

Floor 1 has 15-18 doors if I remember correctly. Building an industry module in the first room (14-17 doors left to open) for 20 industry and an income of 3 industry means that that module pays for itself halfway to the end of the floor (7 doors to see a profit - 7-10 doors left). If you have the module slots you can build a second major module for 25 industry on reaching the third room (12-15 doors left). It will have paid for itself after 8 doors so 4-7 doors left. A third industry module would not be able to bring in the industry spend on building it.
A Food module bought with 30 industry would on a one to one ratio comparison of resources spend not be productive, but the food income will mean you'll be able to reach operate sooner or hire another hero sooner.
So 2 industry and 1 food are a good safe choice.

For 1-3 floors I usually place 1 ind, 1 science, 1 food. Industry allows you to build modules and thus essential. Science allows you to faster learn new modules and thus, more FIS to produce faster. Food is needed to level up heroes, but in my understanding, science > food.

I build a food module and a siecne module only, you alredy get 5 industry witch is enough at start since you will need only one or two minor module to pass the first floor (or none), so I always leave the first floor with an adverage of 30-50 industry and my caracther are lvl 2-3-4 because i got a lot of food and sometime I get lucky and can even make one or two research before i even get to floor 2.

For the basic pod I'd recommend 1 industry and 1 food ASAP.
Your objective is to save up to level your operator to 3(or 4) at the beginning of the second floor, while having enough industry to start out with one of each module. Floor two depends on RNG for whether a 4th module will be worth it so it's usually better to go 1/1/1.
Set your operator on your build path of preference:
Industry for operator-based (3 operators + 1 fighter)
Food for fighter-based or balanced (1-2 operators + 2-3 fighters)
You might want to rush food earlier in case you're lucky with your hero finds.

I used to do 1 industry and then 1 food... and thanks to a critic named Dawnbomb, I reshifted my thinking. Now what I usually do for other floors is build based on the current priority (once you get better at the game, you have a better feel for the value of Ind vs Sci vs Food at any given time), while respecting the average amount of doors left.

But my critic friend had a point when he stated it was more important to simply rush the operator. So I did the math...

The estimated amount of FIS you will leave with on Floor 1, with Opbot on your team, leveling to 3 ASAP, on single player=

Building Industry 1 and then Food 1:
68 Ind + 24 Sci + 47 Food= Net 139

Build JUST Food 1:
54 Ind + 24 Sci + 69 Food = Net 147

Build Food 1 and then Ind 1:
53 Ind + 24 Sci + 69 Food = Net 146

As far as Single Player goes, a single food replicator is the best choice, by 1 industry, hehe. You'll have around the same results with Rakya/Josh because they have the same level up costs but only slightly different wit amounts.

But what about multiplayer? Multiplayer gives you 76 free industry that you don't have in SP! Well, my intuition tells me it's going to be 3 food generators in a row to super rush op, but on hard mode, finding 3 mod slots right away is not always going to happen.

And if you ever want to do the math, the simplest way to remember it in your head is 13,15,17,19,21,23,25,27,29,31, 11th and 12th stay at 31, for the predicted number of rooms per door, with a range minimum and maximum of -3/+3 (I'm simplifying it though, floor 1 cannot have 10 doors for instance).
