Halo Reach Boring?

I’ve been playing Halo Reach and am enjoying it, but it is pretty boring. Many of the missions are at night, so the graphics are muted and uninteresting. The day missions are better, but there is not a sense of wonder, so far. In Halo, we found and explored a ringworld, while in Halos 2 and 3, we dealt with Universe-ending threats, the Flood, religious fanatics, and more. These were experiences out of the ordinary for games and made them more fun than just the combat. So far, Halo Reach hasn’t had any sense of discovery or awe. The troops seem to know all about the Covenant and are mind blown that they are on the planet. Now, I’m not that far along, so the larger, universe threats may come later. I hope so, otherwise, it’ll be hard to keep interested. I know I shouldn’t be interested in the plot, but stories are important for games, in my opinion, which is why I’ve never finished any of the Grand Theft Auto games (among other reasons, like the driving is horrible).
