I have a few questions if anyone is kind enough to answer:
- Each chapters is a sequel story wise to the previous one?
- Are the walkthroughs recommended or you can easily complete the games without one?
- Are the chapters long? becuase 5 chapters seems like a lot
Yes, the stories continue in chronological order, so each chapter is like its own book. Saves don't carry over, as the games are mostly linear, and each chapter assumes you finished all content from the previous ones.
Each chapter has an in-game hint system, except chapter 2 and you will need a walkthrough if you want to complete that buggy mess, but most people get frustrated with it and move on to chapter 3, which has 3 separate downloads that will all need to be in the same folder to play it.
The chapters are all huge, basically full-sized games.
