I have a terrible memory for everything. That is a fact that I’ve known for… pretty much my entire life. Even then some times I still get surprised about how what I remember and what is fact ends up being different.
Case in point Valkyria Chronicles. My memories from the first time I played the game I had an easy time with the early missions and could easily get an A or B on them. Now I decided to play the game again, restarting from zero since I could barely remember anything about the gameplay or the story and the results have been pretty different from my memory.
