I love how much little changes like that, made the game bigger as it is. Bravo for you
BTW, could be possible to check what time is it, in order to make some stuff available (like at 1990, a new kind of weapon can be research) So in the future, some events can be timed in order to make scenarios (at that time a country is defected to aliens, at other a huge alien UFO destroy a city, etc, etc)
