: completed Halo 1's LASO playlist.

: ODST is definitely the easiest one to speedrun, lol.

Hell, I beat ODST in just under five hours on my Legendary run when compiling data for my difficulty balancing thread from three years ago, and I was just playing through normally (and you know me: I don't really speed run). But that five hours includes Mombasa Streets. For the regular levels my total play time was a little over 3-½ hours, so speedrunning ODST ought to be easily attainable if I put in the effort to shave a few minutes off of each level. It'll probably be the only game I actually do get the speedrunning achievement for.

Anywho, I'm getting my TV back from the repair shop Wednesday, so I'll definitely be playing some ODST then.
