Well, I'm on vacation far away from home today, so I won't play it now.
But that reminds me I have to get everything from this game, meaning I must be able to reach the hidden paradise on hard.
I got nearly all the special objects on normal difficulty, but I think I will have to have a second playthrough to beat some of the colossi fast enough and get the 3-4 objects that I lack.
I intend to play it on hard too, as the objects are even more amazing. But my kind of play is not compatible with the purpose here.
Also, on my PAL PS3 (semi hardware semi-software PS2 emulation), SotC has no slowdown at all, it's entirely smooth. Does anyone experience the same thing ? I remember seeing the PS2 SotC, and it had lots of hiccups.
