I fully agree, a starting point just like in EU or CK or Victoria or all their other games. That’s my fundamental problem with Stellaris. Asymmetric starts are just way more interesting than the usual 4x where everyone starts with one city/planet. Also makes the game much more of a challenge without needing to resort to giving AI cheats.
While starting with one planet seemingly fits the theme of the game, as it is like Earth starting to explore the stars, it makes no sense for all intelligent life in the universe to start exploring space at the same moment. Fallen Empires goes a little way to alleviating this, but it would just be better if you start the game with an established universe and you learn more about that universe as you explore.
