Hard to say if I like this or Halo 3 more. 3 definitely perfected the game feel, and I liked the enemy variety a bit more, but Reach is just as fun to play and has probably the best level variety of any game in the series. The space battle in particular was a nice addition. This is definitely one of the tougher game in the series, and be prepared to have some restarts tied to getting blown up by concussion rifles. If I were to recommend games in the series to people, this would be towards the top of my list, as in addition to being extremely well made, the game just oozes its own personal style with the actions of the Noble Team.
