If Halo Wars turns out to be crap, could it ruin the Halo name?

No, I don't think it would damage the name, as it isn't a main Halo game. Halo 4, when it comes, will be unaffected by any spin-off games, no matter how bad. Further, I'm pretty sure Halo Wars isn't going to suck -- competant, at the very least.
