Been playing multiplayer with a friend for a few weeks now. We tried simultaneous, but there are so many issues and out of syncs with it that we didn't feel like we were saving any time with all the reloads. So we went back to classic turns and the game is going out of sync just as often, even on our own turns. It's very unfortunate how slap-dash the multiplayer experience feels on this game. I've played other 4x games that deal with just as much, if not more information, as this one. Stellaris comes to mind. It goes out of sync from time to time, but no where near as much and that game is in real time. While I hope this game can patch in a more stable multiplayer experience I wont hold my breath, but at least It's my hope that future games will have a smoother multiplayer experience.
