I played the Halo series with my friend´s XBox and honestly found the series to be a bit bland and with some glaring flaws. For example, in Reach the stupid Warthog charge against the Covenant and the fact that despite humans being a space faring race, they still use ammunition that is equal or worse than modern weapons (the assault riffle is probably even a poor design when compared to modern rifles). I could go into ther details about the story, but I can wait till some people tell some points which I can debate with. As for the characters, I honestly thought Thel Vadam should have been the main character of the series, as opposed to MC, who barely had any personality, Vadam, grew, changed and evolved with the games. His history similar to the Gladiator. From general to disposable suicide soldier, to rebellion leader. MC stays the same throughout the entire series, barely having any noticeable change. Bear in mind this is not an attack on Halo, it´s more of a question to what you find positive about the series. Maye you can open my eyes or not.
