2/
There will be liquidity pools for each resource that is added
To start they are adding
- IRON
- WOOD
- STONE
- GRAIN (already in game)
Each plot will do one of those 4 items OR you can choose Research or SPS
(Later how you get those things will change too)
3/ You will be able to swap DEC for any of these resources (Grain, Stone, Wood, Iron + Vouchers)
The developer hopes to make it easy to do advanced swaps easily... like Stone to Wood (handling stuff in background)
Ohhh super nice.
