I have to say, I've been a long time Halo gamer. I date back all the way to CE and go all the way through 2, 3 and Reach. I haven't played Halo Wars or ODST yet, but I do have plans to invest in them both as they both have interesting and unique traits. However, in my opinion, Reach is the best game to date. The campaign is epic, yet has a lot of sadness in it. The armor customization is intense and highly detailed, full of combinations. The combat system has new and unique things in it that haven't been used before which changes the tactics in the game. Then, there is forge, which is quite possibly the best thing that I have ever done in a video game ever. A great game all around.
