Halo was one of the first games I ever played on the OG Xbox and probably the reason I got into playing video games. I've played all 4 and can honestly say some of my best gaming moments came from the first 3. unfortunately, at least for me now, it doesn't have that spark it once had. It's lost that "sheen". It should've ended at 3 but I'll give the benefit of the doubt and say 4 wasn't too bad and could've ended there. I just wish it would die off and something new would come along. But that'll never happen cause halo= tons of $$$ and Microsoft like any company wants $$$.
