Indonesia is the most
economically powerful southeast asian nation, also have a
considerable army in comparison to its neighbors and have the
largest population in the region. Perhaps a goal that envolves one of these three aspects or all of them is a good start, like:
be the most powerful economically, military and populous in southeast asia by 1980. The problem with this goal is that exists only two southeast civilizations in the late game: Indonesia and Thailand. Thailand tends to be very weak and unstable during this period of the game, which virtually gives human Indonesia a good advantage or even an easy victory.
Others goals that can be make with this idea are using muslim civilizations. Indonesia have the
greatest muslim population in the world. Changing the actual goal to
Be the most populated muslim civilization by 1950 or
Be the most powerful economically, military and populous muslim civilization by 1980 (although less historical) are good options, because the player will compete with Ottoman Empire/Turkey, Egypt, Iran, Mughal Empire/Pakistan and Uzbekistan, because the player will compete with Ottoman Empire/Turkey, Egypt, Iran, Mughal Empire/Pakistan and Uzbekistan. The mughals, egyptians, iranians and/or the turkish could easily win an unprepared player in one of the described goals.
