I'm gonna disagree with Halo 3 grifball being perfect, but it seemed a helluva lot more enjoyable than grifball in reach. I think the reason for me is that there's a lot more client-side 'trust' in reach which results in more mutual kills and stuff. The thing I liked about Halo 3 - even though I'd rarely get host - was that you could get a decent gauge on what the connection was like, and how to counter it. This took a bit of awareness and foresight to pull off, whereas Reach eliminates this altogether (which is understandable as it makes it less connection-reliant). Just personal preference I suppose. Can't seem to stand playing Reach grifball at the moment.
