Beyond earth was rejected more than Civ 7.Every Civ game had criticism and there is always claims that the previous were better, but NONE had this level of rejection, and we have had Civ games even less polished than Civ VII before, so i dont understand how people can blame polish on this.
Sandbox wasn't the focus of Civ 7 on release, but now one can disable all legacy paths and crises and turn on long ages and enjoy the gameplay free of race and streamlining. And with the continuity setting enabled almost everything carries over to the next age. Snowballing, while harder, is still possible in Civ 7, and conquest is as fun as ever because of revamped warfare. Someone might complain about settlement limit, but in 90% cases it's because people don't know the limit is soft, not hard.
I don't think many people tried messing with settings and instead play the default ruleset, which is designed more towards competitive board game.
