Remastered comes with IGT each level, so we could add up all IGT as well with a real timer and just compare?

I'm guessing you start when the level loads up and stop the timer as soon as the Hyperspace button is pushed?

Honestly given the IGT, I am a fan of IGT only. Then we dont have to deal with movies and load time oddities. Will update my runs and the Rules to reflect if you agree.

I was thinking we could do both. Runs would only be approved if you added up your IGT (down to the last second you see before each level fades to black). But if one wants to do both, we could put an RTA option in another column.

For Classic, we have to do RTA, (unless there's an IGT I'm missing).

That makes sense to me. I generally dislike two methods, but I want to be respectful to people with slower machines where load times might be a factor.

I will redo my run and set up the boards on Remastered to match.

To clarify, the IGT would be the only one that would truly count, the RTA option would just be next to it in the same website window ( people can sort through it for record's sake.

For example, take https://www.speedrun.com/hades which has Real Time and In game Time but only IGT counts.

And what is the point of RTA if IGT is the official one used and RTA doesnt matter?

Eh, it's ultimately up to you. If Homeworld speedrunning ever flourishes like the others, some people might want RTA because it's what they're used to.

I assume you are talking just about individual levels (IL)? Full game runs should be RTA, because time spent between missions matters too, and people could also just reload individual missions indefinitely until they get good IGT times displayed for each.
