Players praise the strategic depth, expanding progression systems, and meaningful differences between faction builds. Common complaints include poorly explained mechanics that encourage using outside guides and a premium shop some players consider intrusive. Some also report black screens, heavy PC resource use, and incompatibility with Apple silicon Macs.
