Fortresses have such a high energy cost (as well as metal and crystal) because they are very cheap in terms of firepower-for k. They are not supposed to be deployed at full caps, except by really big empires. Generally, fort IIs or IIIs are improvements rather than new units. I see no problem with the current state of forts.
I agree with this in principle.
My problem is that I still feel they are too energy intensive, at least for a single homeworld start.
I agree that you should not be able to build a cap of forts with only a system or two, but I control 8 systems. Why am I struggling to build the cap of fort Mk I's still? And forget about Mk IIs if I want any sort of mobile fleet.
With 8 systems (1 HW and 7 captured) energy collectors are giving me 1.2 million energy. A cap of Mk I forts costs 450,000 energy and Mk II 480,000 energy. If I build both, that leaves only 270,000 energy for everything else.
Now, for a single homeworld start an 8 empire system is pretty big. I feel I
should be able to support the forts at this point from a game balance perspective.
The reason I asked about multi-hw start is I believe the collectors multiply their output by the number of homeworlds. So while a 4 HW start does have higher energy requirements, when you capture a new system the new energy collector increases your energy total by 600,000 energy while in my single HW start, a new energy collector only gives me 150,000 energy.
This means that a 4 HW start can run a cap of Mk I Forts off a single energy collector and have energy left over, I need 3 energy collectors to run the same cap and don't have any left over energy at all.
I think in the end this comes back to the fact that while the new energy system is a definite improvement, it's never really gotten the polishing fixes it needs and it is showing in this specific case.
However, as we are not getting a major rework to energy before 6.0, I'd like to ask that the energy requirements of forts be lowered as a 'quick fix' so I can actually use them in my game.
Two other alternatives would be to make metal converters more efficient so I can use those to support the forts without crippling my economy, or give the forts an ongoing maintenance costs of metal and crystal as the trade off for how cheap they are from a K-for-firepower perspective.
In the end, this ends up being an opinion of how easy it should be to deploy forts I guess.
However, for a single-HW start, that question is reduced to "how many fort Mk I's can I build?", I can't see anyway of a single HW start being able to build Mk II or III forts ever as it currently stands.
