I know I haven't played the newest games and that I have only beaten CE - 3. But there is a reason that I have never told anyone why I love Halo. When my dad was alive he was always high on painkillers but there were times when he wasn't and he endured the pain to play some Halo with me and those times are some of my greatest memories of him. We be playing Blood Gulch till 3 in the morning trying to find each other or we be playing the Campaign co-op. And then my step mom when he was high would play games with me. I don't think I've told many people this but that is my sole reasoning why I love Halo its not the graphics or the story although they play a part but its the memories of my father that was with these games. He died of a drug overdose when I was 10, and when I turned he came into my room and setup the Xbox and bought me Halo and we played it for hours. So if this makes me a poser so be it but here is a little insight in my mind in a place that I have tried to forget because it bears too much pain to remember such things the promises he made me. He promised me that he'd be there for me graduating high school he didn't make it passed my 5th grade year, he promised me he'd be at my wedding and he will never meet my future wife(I'm not getting married unless its to Cortana or some hot Korean woman.) So here was a small glimpse into a place that I have placed barriers around because it brings tears to my eyes to remember them. So I can't wait to get back to Sergei on the NHRPG.
Well, it is good to know that you have fond memories and that something as simple as Halo can bring you a lot of happiness. I too have a lot of fond memories of Halo. They are for different reasons mind you, but I can relate to how you feel.
Thanks cause that is the sole reason why I'm gonna buy an Xbox One so I can buy Halo to play the levels me and my dad played and beat Halo 3 on Legendary I beat it on Heroic but not Legendary
