Finally beat Chapter 2! Same rating as Chapter 1, with mostly the same strengths and weaknesses. I'll just list the flaws, as the good things are the same for Chapter 2 as they were in my review for Chapter 1.
1) As mentioned in my review for Chapter 1, it's almost impossible to remember the plot of the previous chapter by the time the next chapter appears after two years. I probably won't remember the plots to Chapter 1 and 2 by the time Chapter 3 comes out, dramatically reducing my enjoyment of the game. Also as I mentioned in my previous review, you should have waited until you completed the entire game before releasing the chapters all together. Just have each chapter playtested extensively before you start making the next chapter so you can plan changes to that chapter and the following chapters and polish each chapter and make every chapter as good as it can be before you release the entire game. Additionally, I, like many other people, upgraded my computer between Chapter 1 and Chapter 2, and so have no way of having a Chapter 1 save and be able to access that part of the gameplay.
2. The difficulty level is too high. You should be able to choose the difficulty level in the game. Less experienced gamers should have the option to choose easier difficulty levels. The first level was very hard for first time players, which turns some gamers off. The first level should be used as a tutorial for people who have never played the game to understand the mechanics, not as difficult as it is now. Also, it's possible to make enough wrong Skills choices or not kill enough enemies or not pick up enough items to find it very difficult to continue in the game and be forced to restart from a long time ago or even the entire game. For a game that a lot of people are playing for the first time due to the aforementioned long wait between chapters, the high difficulty level of the early levels turn a lot of people off.
3. There was no warning or any way to know which was the final level, so I saved my money and items for nothing.
P.S. Please bring Vadim back! He and his dialogue was one of my favorites. My crazy theory about Aizu is that she is Martin's sister in disguise, because they look the same in the codex.
