Indonesian - Bahasa Indonesia has roughly 30 million native speakers and 140 million who speak it as a second language. Based on Malay, it has evolved into unique mix of many dialects over time. At one point it was heavily influenced by Dutch during the Dutch East India Trade in the late 17th century. As a result, it is still relatively simple but has borrowed words from many cultures. Fun fact: Indonesian - Bahasa Indonesia is included in 55 languages available in outer space. It is stored with other sounds and images from Earth on a golden disc on the NASA Voyager satellite.
