I might need to be shot for not knowing, but what kind of game is Halo? My xbox is my first real console system since the original NES (the Saturn I bought one game for doesn't count!), so I'm just getting back into the swing of all the titles and what's good, what's not, etc. I kinda feel like I'm sinning by not having Halo when I have an xbox, so someone tell me what kind of game it is. I've only seen pictures of the game and it looks like a shooter game to me, but could also be a RPG. Is this an involved game where you hunt for clues and things or just a really good graphic shooting game (something like Doom)? Fill me in please so I know if I want to go buy it. Thanks.
