Is there any way we can use IGT instead of real time? As far as I know, the IGT that's displayed after each stage is accurate and, importantly, takes into account all deaths. Since I'm going to be running on PS4, this removes all hardware differences from the equation, loads etc. Thanks!

We use igt for levels but theres no igt for the full game. Unless u manually added up all the times I guess.

I never ran the full game, so ill let Brooks share his opinion.

Slowest response ever! I'm not actively speed running anymore, but just checked in and saw this, thought it required a response in-case anyone in the future does decide to do full-game runs.

IGT is actually a really smart idea (I didn't even consider it for full game when I started, but makes perfect sense) Each level has it's own timer, accounts for deaths etc. I'd just add up all of the in-game times for each level to get a final IGT, that isn't affected by hardware differences/loading times.

For the four existing runs (five with 100%) that use real-time. It'd be easy enough to just watch their videos, add up the times for each level and edit in the IGT for each run. Just a little time consuming.

I wont make these changes now, since nobody is actively running full-game at the moment anyway. Plus it's been four years since I've played. Maybe there is an issue with using IGT that I haven't thought of, or have forgotten. I'll let someone whose played it more recently & with a fresh pair of eyes have a think about that.

If/When anyone decides to pick this game up seriously, I do think you should consider switching them all over. It means you'll have to do a little bit of work, but there's only five full runs total, so it's not entirely unreasonable...
