The Mass Effect Trilogy is considered one of the best video game series of all time, with great worldbuilding, storytelling, and characters. While much of its storytelling remained consistent throughout the series, its combat and game design changed from game to game, losing many of its classic RPG elements from Mass Effect to adopt more action-RPG characteristics. With its combat varying so much between the games, there is also a discrepancy in the quality of the boss fights across the Mass Effect Trilogy, with some criticizing their repetitive nature and boring mechanics. This is a weakness in the Mass Effect Trilogy that needs to be fixed in Mass Effect 4.
