I know that we all disagree when it comes to different games. Some of us like it more than others, and some hate it.
To make matters simpler I propose a new personalized rating system, which is pretty simple to calculate. Call it the Sama Rating System:
Game Score = (Fun - Pain) x (Story + Multiplayer)
Fun = Number of fun portions throughout your experience
Pain = Number of tedious (painful) portions you suffered in your experience.
Story = Rating you give the game's single player, using a one-to-ten scale where ten is total enjoyment.
Multiplayer = Rating you give the game's multiplayer aspect, using a one-to-ten scale where ten is total enjoyment.
NOTE: In case of games that include only a single player or multiplayer mode, you can rate it using a twenty-point scale. This ensures a more balanced rating system.
