The amount of time you should spend at Comic Con varies. Some people might be satisfied with half a day, especially if they have a specific goal in mind. However, for those who want to soak up all the atmosphere and experiences, it's not uncommon to spend two or even three days.
The time it takes for writers to work on comics really depends. It can be influenced by factors like the complexity of the story, the artist's schedule, and the writer's own pace. Sometimes, a simple comic might only take a few months, but a more elaborate one could take over a year to complete.
The time you can spend on the class story in SWTOR varies. If you rush through, it might not take too long. But if you enjoy the side quests and take the time to soak in the story and world, it could take several weeks or even months.
The time I spend on my visual novel fluctuates. On average, I probably put in about four hours a day. But there are days when I'm really into it and work for much longer, and days when I don't touch it at all.
