Well, here are some of my modified rulesets heavily based on several different mods (thanks, everyone!) and some relevant information (I'm using the excel file to organize things: just adding things when I have some free time
). I'm just messing with a lot of different rulesets and testing them so don't expect any quality
I've modified a lot of different things and trying to rebalance everything as I play the game so I don't think explaing all of them are useful (anyway, what I want is Your mod's development
)
(1) I thought about two different approaches about weapon technology (since anyway I didn't want to throw out the Gauss weapons). First, giving them different traits so that they can be both useful even at later games. Second, setting up a general hierarchy. Actually, both approaches can be fulfilled at the same time. The difference comes from the weight one wants to put between them. I decided to put more weight into the second part, but I find no reason putting more into the first part is not equally viable.
(2) For the justification, well we always can find sound reasons to back up things, you know
I justify every mods when they can bring fun and challenge, simple that is. Technically, as I said before, I'm modifying the whole structure so that everything can go well with each other. For example, I'm going to increase the AP and HE resistance of later aliens so that the effectiveness of standard issues and Gauss weapons will dwindle as time passes by. It is really nothing but an option depending on my previous decision. So if you want to put more emphasis on the diversity of weapons, you might want to also diversify the armor types of aliens so that each weapon can make some voice even later on. Here comes the variety of mods
(3) For the craft and craft weaopns, I think I need more experience about UFO battles. The hot potato is of course the avalanche. Due to its long range, I really didn't feel any reason to build a more durable craft. I'm going to change it drastically, but now I just need more experience and observations
Hope it helps.
P.S. The buckshot ammo sometimes works and sometimes not. I guess it might be related with the range as you've said.
