Based on all the information coming out about Halo: Reach, it seems that Bungie's basic philosophy has been: 'The sequels to the first Halo sucked. Let's fix that.'

Reach seems to continue this idea while trying to invigorate the franchise by introducing greatly improved graphics and additional gameplay mechanics
