Really nice mod. I love how it adds all the new stuff making the game much more diverse and interesting, while at the same time it makes it much harder and longer.
Although, I believe there's a nasty bug somewhere here...
At first I was playing Veteran Ironman with only Final Mod enabled (+some options), afters few months of doing OK I finally got my butt kicked by some aliens and lost all my men and ship in terror mission. Nothing from what I couldn't recover. I've started to rebuild my strength, but at the end of the month instead of losing some income I got information that X-Com is no more and aliens won. Well, "I suck" I said to myself and started again...
Second try with the same settings. Doing fine, few months passed, MiB starting to show up. Had some trouble with them and with aliens, lost some men, but it wasn't a disaster. Waited for new month to get some cash and upgrade the base, but suddenly I got like -4500 score out of nowhere. Next month had some ups and downs, but it wasn't that bad, still it ended in X-Com being disbanded and alien win.
Third try, same settings. Doing really well. Few months (3-5, can't remember) passed. Kicking alien asses hard. Nice month for me - won terror mission with only one soldier dead, shot down couple of smaller UFO, all crash-site missions won with no casualties. Ignored one very large UFO, but didn't have a power to even scratch it for now. Expected like 700-1000 score at the end of the month, but I got like -4300. "Where the hell did that came from?!" asked myself. Well, next month I tried even harder - everything went great, but at the end of the month I still somehow got terrible score and game ended.
I thought that game was bugged, but when I tried it without the mod, it's almost a year now and I'm constantly getting around +1000 to +2000 score each month, so it must be something with the mod.
For Final Mod I was using latest nightly at that time, which was "2014-07-09 18:15" build I believe. For clean OpenXCom I used current nightly. I'll try how the mod works on latest nightly when new version (with updated MiB) will be available. Hopefully that game-breaking bug will be gone by itself by that time.
Best regards.
