No particular reason to give 5 stars. I don't know how to explain it. I played Halo 3 back in 2007 and I just fell in love with it. Stood outside GameStop (could have been EB Games) with two friends for 5 hours waiting. I don't know, Halo and Halo 2 didn't pull me in like Halo 3 did. Then there is Reach....😏
