Just want to add, while I like persistent, aka perma death, I like having a "wounds" thing too. You, know like in X-com how you can have agents bleed out, but if you are fast enough you can save them. It always adds a lot of drama, instead of just having binary; alive or dead.
Thanks for pointing that out! That is freaking tempting to include. However, I want to see first the impact that the current wound system has on units. As it currently stands, a wounded unit can be rendered useless if critical or enough body parts are wounded. For example, getting hit in the head will severely compromise the unit's ability to fight or operate items in general, and having both legs crippled will heavily affect its movement speed. So, I want to see if these effects, while not time based, do provide some of the drama you describe, because, having a unit incapable of moving while exposed to enemy fire, is prone to recreate some dramatic moments, I think.
