Halo Combat Evolved because story line is the best ever seen by a shooter and Halo 3 was rushed because Bungie knew we Halo fans needed a new one because, by 343 Guilty Spark's words,"Why the ark of course." it leads you presuming another is coming and I think Halo 3 played like Halo 1 too much and Halo 2 so I just got skull idea mastered so you can activate them, forge for map making, armor like my green + orange hyabusa and many others, and new wepons like the sp and g-hammer so Bungie might as well made an expantion. Halo 3 dissapoints me beyond extent so Halo 1 all the way!
