Final answer:
The typical clues that a video game has been finished include a credits sequence, a congratulatory message, unlockable content, and a 100% completion percentage. Continuing to explore the game world does not necessarily mean the game is finished.
Step-by-step explanation:
When someone finishes a video game, there are usually several clues that indicate the game has been completed. These may include a credits sequence that rolls at the end of the story, a congratulations message from the game, unlockable content such as new game modes or additional levels that become available after the main game is completed, or even a completion percentage that reaches 100%. However, some elements such as continuing to explore the game world, finding collectibles, or simply seeing a 'Game Over' screen would not typically indicate that a game has been fully completed.
Therefore, if Marcelina is continuing to explore the game world or is engaging in post-story side missions, these activities would not be clues that she has finished the game. Completing a game generally refers to finishing the main storyline or campaign, not necessarily collecting every item or exploring every part of the game world.
