I think it's fine the way it is. I feel people might decide not to speedrun the game if they realize they have to measure the time in real time.
By the way, how is time measured in the game? Do you use the sum of deltas of time (which can be less accurate, depending on how you do it), or do you constantly display the time difference between when the run started and now?
I would prefer to keep it IGT, I think it's more accurate then RTA would be. I think what Risible is referring to is the effect of the game slowing down for a couple of frames whenever you take damage?
For simplicity's sake, I'm removing RTA times so they won't show up on leaderboards, since submissions are coming through with RTA times. Since there's no guidelines/ground rules for when timing ends on RTA, it's impossible for me to confirm/correct RTA times anyway.
So, the issue has come up once again about Real-Time versus IGT. I've made a strawpoll for it, and I heavily suggest all runners weigh in with their thoughts
