Twice regarding throwing mechanic:
- We can have a nice throwing range, yet we don't have other means than dropping an item to the floor if we want to pass it to a comrade in need. Is it possible to make throwing mechanic universal, ie. making the switch button to the throw mode always available? So we can throw anything having currently on hand - trauma kits, weapons, ammo etc., not only grenades...
Would be ok if it reuses grenade throwing animation and just adds the same bags to the floor (though if useful maybe color party bags differently?). Tactical maneuvering it opens up seems worthwhile to me.
- As you are going to implement weights of items anyway, are you also considering to have it to be part of throwing distance formula? So lighter things at the same Prowess can be thrown further.
For example, something like:
Max Throwing distance = TConst + floor(TMod x Prowess / WeightOfItem)
So if TConst=1 and TMod=2 (just arbitrary numbers to give an example), then:
At Prowess 3: you can throw 2kg item 4 tiles, 20kg item 1 tile
At Prowess 10: you can throw 2kg item 11 tiles, 20kg item 2 tiles
etc.
The weight of explosives and other items being also part of difficulty balancing.
With those two points it could be also easier to balance stricter inventory weight limits, because party members have more options how to pass things between themselves, can assign a character to be a pack mule, and so on.
