For those new to this thread and game, I can honestly tell you that for me it was "came for porn, stayed for the game". If you have a couple of hours to spend, you'll get caught in the story. You can also google the name of the game and use the wikia you find for maps and special character interaction that give relationship points. Making a notepad with chests you can't open will also help you. Before you start the game, you should know you have 4 ways of playing the game: 2 choices - eastern or western edition (pictures are drawn differently) and good or evil. You also have the possibility of continuing your save from LOQO1 to LOQO2 and so on.
You can also use an early save in SGEdit (found in the game folder) to add gold, equipment and change stats. There are some fights that you must lose in order to get a special CG/event while you have a specific character in your party.
Have fun, ik I did.
