Halo reach is a mixed opinion kind of game. Some people like it while others didn't so with that being said I don't think it's good to post game types that some people probably don't like. I personally dislike headhunter but I did wish that invasion was in Halo 4.
Personally, I think Halo Reach had a better choice of game types than halo 4 when it first came out but the game types (halo 4's of course) are really getting better.
Every game is overrated because the Internet hates everything and wants anything that's going up to go down. Like a true villain.
