  • Technical Performance
    Some users might experience performance issues, especially when dealing with larger spacecraft or extensive mod collections, requiring a powerful PC for smooth operation.

    Once the initial excitement of discovering space has worn off, some players may find the game becomes repetitive as the core mechanics remain largely unchanged.
