I agree with Samu. The Steam version is a completely different game. Differences I have seen: Fastfoward feature, lack of CG scenes, and minor gameplay differences. I've also seen a few glitches in casual playthroughs, such as not having to use the Loose Board in Chapter 1, and items appearing in player's inventories before an event. Unfortunately, it didn't seem like any of those glitches would help in a speedrun, as they were actually hindering the players from progressing when I saw them occur.
On a side note, I think PS Vita and PS TV should be added to the run options for the PSP version of the game. I know I've done all of my runs on the PS TV, but have had to mark them as PSP.
I added you as a mod. Also, glad to see others running this game~
First of all, sorry for the late reply!
I understand your concern with the IGT. As not many people were running this game I haven't really tested anything. The time difference being only 12 seconds, do you think it could be because of a variance in skipping cutscenes?
I've have been thinking we should make a category specifically for this run since it's the only version able to use superjump, as far as I know.
Anyway, I don't mind changing it. I'm actually the only active mod as far as I know (I had to request mod on the main forums to even submit a run). I'm also authorized to add moderators, so If you'd like to be an Ico mod as well, you're more than welcome too.
I'd like to be a mod for Ico. I run this game a lot and there's been no runs posted yet. I've been waiting a while for mine to get approved and I already have gotten a better time. I was hoping once a run gets posted it will drum up some more interest in the game. Anyway, thanks for the consideration~
