Last fall I found myself attempting to force a few playthroughs with mass and volume enabled and really did not enjoy it. The menu system was clunky and the flow of the game was really interrupted. Now, 4/5 months later, I still do not really like it. but! I am REALLY enjoying the CPU system. The basic limitations are not terrible(could use a tweak or few) and I love the feeling that I can "Build to address a limitation."* Feel free to be more direct with the scaling - introduce a tier 5, 6, 7 extenders and have them be high unlocks on the tech tree, very useful, and with the lower tiers not being as expansive. One thought I had was maybe addressing how the communication is being delivered to the player as right now the CPU total and the devices using the CPU are listed on two different screens: vs <- on the first I get the total AND usage, on the second I only get usage. It is a touch un-intuitive and a little scattered. Anyways, generally positive feedback here. Keep refining and improving this system! * - This could be done with mass and volume too; add in some inertial dampeners or mass void projectors. That way I could build to address those challenges outside of just adding more thrusters or storage containers. This would bring back the potential of smaller ships which have largely vanished from my games with m/v enabled except at the very beginning of a new game.
