I understand your perspective, but for the purposes of the type of game this is, counters must exist and scientific thoroughness can only be a force bonus. Next turn, System efforts will mean that the plague and the EMPs are almost certain to have less effect, but similarly, many players noted special filters for the waterborne mind control nanites, and the airborne ones I made the call would not be terribly effective beyond a small distribution radius—good for quieting you populace and stirring up problems in neighbors, but not affecting the whole world.
As for the assault, there were paradrops with EMP cover and pushes through Russia and Bulgaria, not direct assaults on your beach defenses. At the same time, as a nod to the defenses, I left Great Britain largely unscathed. And as I suggested in the update, the skies over MDI nations did not fully cloud until near the end of 2061.
The 60 ASP or so you have invested in tech has done a huge amount of damage to MDI economies--20 ASP, off the top of my head, which could cost as much as 60 points to fix, and on top of that, you flipped Mexico, shut down dissent in lands you occupied, get half price divisions, squadrons, and groups, and have had considerable casualty bonuses for much of the game. Not to mention, you are now holding the future of the world hostage. I believe all that is considerable payoff on investment.
Ah well. I could have threaded the needle differently, and perhaps I should have, but we will be done on Monday.
