Valadian patches seem to have very low richness. This is an issue by itself because moving expired miners is one of the least fun parts of Factorio. Space age added several things (lava metals, infinite fruit, reduced big drill drain) to directly address expired miners being not fun.
Science needs a lot Valadian but we don't need much science. So it's inconvenient but no big deal until considering the Crusher Upgrade. These are 1.5x faster which makes common Crusher Upgrade worse than a rare Crusher. So we'd need enough Valadian on the map to quality recycle into better Crusher Upgrades for them to be relevant.
In the other thread Edenstudent suggest 3 or 4 module slots, 3 feels good, 4 is maybe too many. This could be another way for Crusher Upgrade to be preferable to a high quality crusher.
Also there are there are prolonged periods of silence, not much music associated with the Surface. The available tracks are great. I understand than music is a completely different process and finding suitable & available music can be a challenge, but a more complete soundtrack would be worth a lot to me.
Overall I am enjoying the early version, it's a good project.
