Halo 3 is the only Halo game who's campaign I have never beaten other than Infinite, which I haven't touched and probably never will. I was working on fixing that, deciding to play through each Halo game in order of release on legendary, but I got side tracked. I had planned to first beat the whole Mass Effect trilogy on insanity before returning to Halo, as I've only every played the first game, but then I got side tracked again. Now I'm playing Kenshi. It's no wonder I never finish any game series... I always have the desire to restart from the beginning of a series each time, but have an attention span this small.
