In my honest opinion, I think the time for WO 4 runs should be IGT, since the game offers an internal timer for missions and load times may differ from platform to platform.

That is a good idea, I'll add the IGT timer option so we can use both timers.

Can't believe I didn't think of that sooner.

I thought the Idea while was playing the game casually, because I wanna see how much time (In game) I was spending in every stage (took me around 13 hours IGT to beat the game)

IGT is good for NG+, where all menuing is kinda pointless. In NG, it matters a ton more, as you need to check weapons, use GP's, do camp upgrades, pick support teams, etc. But in NG+... It doesn't really matter, sense it just means who can skip scenes faster

To add a little more to this. I think RTA at all for this game will get kinda boring. It will quickly be, just to see who can get to each dialog block faster. There are ways to shave time off of this in IGT, but not RTA. Routing for RTA is easy peasy, routing for IGT is much, MUCH more tricky
