Long war is too long imo, I edited the research ratio to being a little less slow.
Later on it's fine, as once you get a few laboratories & scientists it pulls ahead - but until that happens you have to go months & months before you even get lasers & basic armour.
I had a fully upgraded base (almost all slots done with x4 bonus) well before I had any tech, this meant that as soon as the research credits came in I ended up moving from lasers->plasma in no time at all.
I toned down the early research requirements (by a fair bit) & increased the later ones (but about half) - this provided a far more satisfying experience. I also reduced the injury/rest timers by about 50% - as those 35 day injury's really start to add up).
