I've been playing these games for days now. I always get stuck at a point near the end of each game and it takes me hours to progress. With most other games I would've just looked at a walkthrough, but this series is so extremely complex that it almost has the opposite effect. Makes me say "No, I'm going to finish this on my own" and then I don't feel so bad about all the escape games I've given up on in the past...
