I played through the Playstation version of IS a little under two years ago and the encounter rate coupled with the dungeon design do annoy at times. I found it to be bearable, more so due to the overall quality of the game than any sheer tolerance on my part. I also remember being perplexed that I didn't enjoy it nearly as much as EP, which I had played a year prior to that. I enjoyed both of their stories to about the same degree and, as I recall, they play and even sound very similar, so the lukewarm response to IS relative to EP seemed a bit odd to me. Regardless, some redesign would have gone a long way with this game but sadly that isn't the case. My preorder has shipped, though I doubt I'll be playing through it again so soon.
