Anyways ... this doesn't seem nearly so complex now that we have a few more bits of information; it should be easy to clear up by maybe a few more simple answers to simple questions.
The total space in any section of a 'mech: defined by number of "critical" spaces in a tabletop 'Mech record sheet. This amount of space cannot be changed.
Everything OTHER than weapons must fit the amount of unused space and tonnage in the aforementioned section and otherwise follow all other incidental tabletop rules that might crop up (for instance, can't mount jumpjets in the arms or head, that sort of thing).
INSIDE that total space in a section of a mech there are special spaces which PGI is calling "hardpoints," even though they do not behave like MW4 style hardpoints in most aspects.
Inside of these "Hardpoints" are the only place that weapons can be mounted. You STILL must work within the aforementioned "total space" in in whatever section of the 'mech you are working in; you cannot put in weapons larger than the total space. You also can not put in weapons larger than the unused free space in that section.
They ARE NOT (developer, someone who knows, would be nice to confirm this) putting in only one mech for each chassis and trying to make it "work" for all of the many variants of any 'mech in the lore. They are putting in multiple variants of each basic chassis.
Each variant has a unique set of hardpoints. The number of hardpoints in any given chassis DO NOT CHANGE IN NUMBER and may not be moved around the mech from section to section.
Developers, am I right so far? Simple stuff, anyone can follow this!
Now for a few simple questions for clarification:
Hardpoints: are the at least like MW4 in that you can only put energy weapons in an energy hardpoint (weapons type restricted)?
If the hardpoints are weapons type restricted, can the "type" of a hardpoint be changed?
Hardpoints, do they change size?
If hardpoints can change size, can all hardpoints change size to take up all of the free space in any given section in a mech?
If Hardpoints change size and can take up all free space in the section of the mech they are mounted in:
A:Must that free space also be contiguous?
B:Or may hardpoints expand size using non-contiguous free space inside of a section?
It was stated in an earlier thread that the hardpoints would have further restrictions on what they could mount that are determined on a per-chassis variant
Keeping in mind that we are working inside of the already mentioned restrictions, what is the basic guiding *concept*
that guides the team in implementing these further restrictions
on any given chassis variant? You have already mentioned that you're doing this, so there's not much cat to let out the the bag, I would guess.
