When you played through each game for the first time, did you use any outside help or figure things out on your own? Be honest now, no taking credit for getting along on your own if you had help.
I used some maps in PSI and PSII. They were easy to get lost in, especially PSI. I went through PSIII and PSIV without any help. For PS Adventure, I used the first translation/walkthrough because I couldn't play it otherwise.
