I disagree with some, but also agree with some.
What's the big deal here?? It's an opinion article, relax. We're all entitled to one.
Always thought Halo was incredibly over hyped. I know many agree. Nothing special about that game .
-Established the modern FPS control scheme for pretty much every FPS that followed it (Halo:CE).
-Clever artificial intelligence, making the game an actual challenge.
-Set the bar for online gaming on consoles (Halo 2).
-Set the bar for the content in games (Halo 3 had 4 player online co-op, solid campaign, map editor, replay video editing and saving, great playlists and party system, free DLC, etc.).
If you played Halo long after it's release, I could see how you would feel that there is nothing special about it since it influenced so many games after it was released, where it no longer feels unique.
