I really do appreciate others thoughts, as with all things it's an iterative process that's largely been me saying "that's not quite right, do this..."
1) The early versions looked horrible and jumped about the place.. Visual style took a while to take form, yes generated, and the only effort I put in was directing it. I felt it was at a stage I could upload it. Version number is only so high due to many, many, internal tests.
2) Almost certainly will require balancing, I didn't want skills to have to be maxed to progress, but I did want some gating. This is why, currently, skill points are abundant. It's not quite ready for a balancing run as I still think there is scope for more talent trees.
3) So, this was borne from another mod I saw, and I thought why not have it as a skill. Thought process behind this is that I don't really use them as an active play style, but if the bot network has delivered them to me why not. I could probably make it more optional, I am flexible with changes, but wouldn't want a tonne of excess points for capstone skills (research prod is almost definitely over powered). That said, this isn't for people in their first or second run, I want to add more flavour to it. At some point it be the case it is balanced a bit by "you get this but biters get that", this would still be an option to have the skills mod as is, but allow for a challenge to exists still.
Honestly, I am just happy even one other person wants to try it, uploaded it on a whim, not expecting anyone to care. If you have ideas feel free to make suggestions, for the time being the changes will be quick as it's most on my mind with 2.1 main branch release at some point - hence why it's focused on that and not 2.0.
