An American football simulation from Microsoft, NFL Fever transposes the NFL to the original Xbox with a full franchise mode, an accessible play system and a presentation polished for its day. The clarity of the phases, the depth of the playbook and the solidity of the management made it a credible alternative to Madden at launch. The presentation and the AI have aged, and the lack of a sequel left the series unfinished. A good football simulation for nostalgics of early 2000s NFL on Xbox.
