Neighbor Crossbreeding
Plant different strains side by side and they influence each other's offspring.

No.125Rust01The core loop
Action → feedback → next choice- 01Collect different strains
- 02Plan the neighbor layout
- 03Wait for crossbreeding
- 04Select the best offspring
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
A center seed has 2 slow-growth genes; 4 neighbor slots are free and the player has 3 fast-growth plants.
- T2
Turn 2 · The player chooses
The player surrounds it with the 3 fast-growers, leaving one slot empty.
- T3
Turn 3 · The feedback
After the cross phase, both slow genes flip to fast, and the gene readout updates.
- T4
Turn 4 · The next decision
The new strain is planted alone as the base for the next round.
How it plays
Plants are influenced by their neighbors during a certain growth phase, and offspring can inherit nearby traits. Players control which traits can pass by arranging layouts, gradually breeding the strain they want.
What the player weighs
- Surround with good neighbors vs. conserve rare plants
- Chase one perfect trait vs. keep diversity for later
02Start small

03One mechanic, different implementations

Rust
Plants carry several genes (growth, yield, hardiness and so on) and are influenced by nearby plants during a crossbreeding phase; players build dedicated layouts to breed ideal gene sets.

APICO
Focused on beekeeping, it also lets flowers produce new varieties through adjacency or pollination, though I'm unsure of the exact flower-crossing rules.
The difference worth noticing
Rust's crossbreeding is hardcore stat optimization; APICO's leans toward relaxed collecting and discovery.

04What could you combine?
Tie to seed reinvestment: each harvest you choose how many seeds to keep as neighbors, trading breeding speed against income.

Setting the Stage to Breed
Animals won't breed on a whim; environment, timing and partner all have to line up.

Habitat Capacity Check
Before adding an animal, check whether the space can take one more.
