any suggestions on startiing out this game ?

United Empire is a great faction to get started with, they don't really have any hard to learn special features, and their unique thingy, buying out everything with influence, makes getting into the game more comfortable.

Sophons would also be good to start with as they are fairly straightforward. they get a science boost for researching technology before other factions, have decent ships, and their faction quest gives decent rewards. 

First, welcome to the community! Pull up a chair, settle in with a cup of whatever your favorite beverage is and stay a while! 

Second, I recommend playing the game alone for a little bit to learn about the factions and the basic flow of the game, the user interface and how quests, pirates, minor factions and combat work. 

Third, to get a feel for the basics of the game I'd recommend starting with the United Empire, Sophons or even (to a lesser extent) the Lumeris. These factions use most of the systems in the game in one way or another and don't have any traits that modify or ignore these systems (the Lumeris have a special ability to sell and buy colonies and outposts but it's a minor enough change that it won't affect your learning of the game too much). 

Finally, I'd recommend asking questions, lots of questions here on these forums or in the Steam Community chat for Endless Space 2 or on the community Discord for Amplitude Studios, a link to that server is discord.gg/amplitude.

I hope this helps you get your space feet under you and once again welcome to the community!
