Playing through the full Mass Effect trilogy on the same save file has to be one of greatest, most unique experiences in any form of entertainment. The 'Star Wars' of the video game industry, Mass Effect's legacy will be felt long after the final Xbox 360 has been manufactured. The first Mass Effect game was an Xbox 360 exclusive until the multiplatform release of the combined Mass Effect Trilogy, and for a long time was the real killer title for the console. The space opera action RPG was reminiscent of Bioware's Knights of the Old Republic games, in the form of a fresh new IP with exciting combat. Even after the success of Mass Effect, the sequel lived up to the haughty expectations. Combat was refined, the world was expanded, and players continued to be faced with some of gaming's toughest decisions. Mass Effect 3 continued the high quality gameplay and impressive set pieces, but unfortunately let down the majority of the fan base thanks to an underwhelming, insulting final few moments. It's not all about the destination though, and the Mass Effect trilogy sent players on one hell of a journey. Commander Shepard and the rest of the loveable Normandy crew were able to provide a strong emotional core to Mass Effect, the series that defined a generation.
