Isn't there already a weight limit - soldiers can only carry so much, and the skyranger can only contain a certain amount too. Or have I missed something?
soldiers - yes
craft - no
currently, it is possible to load a craft with
everything you have in your base.
I agree with the OP. while the 80-item-limit is very artificial, some kind of limit does add to the decision-making part of the game. It is kind of hard to implement this in a way that is consistent with the vanilla feeling though... so the "advanced option" approach would probably be best.
I vote for the following:
advanced option: loadout limits:
1) (default) 80 item limit for craft, no limit for base defense
2) (vanilla) 80 item limit for all missions
3) no item limits
4) craft loadouts limited by weight
my reasoning: some people might actually want a "full vanilla" feeling, hence #2.
item limit in base defense makes no sense at all, hence #1 (as-vanilla-as-possible-without-being-really stupid)
we don't have engine limitations, hence #3
for a "realistic" approach, an equipment weight restriction makes the most sense, hence #4
(for #4, perhaps it would make sense to calculate the weight limit by
multiplying available soldier spaces by a certain "equipment weight per soldier" number? I wouldn't want to add another number to the craft ruleset, so this is probably the easiest solution)
