Are the hours long? Yes.
Does it require specialized skills? Yes.
Is it physically grueling? No (unless you count sleep deprivation).
Is it emotionally draining? No (unless you are working on games that conflict with your personal beliefs).
I agree with Ed's response that you should figure out what you are good at and study related skills. Broadly, game developers fall into one of four categories:
1) Artists: skills include pixel art, 3D modeling, animation (2D and 3D), graphic design
2) Software engineers: skills include programming, software systems design, database design, mathematics
3) Game designers: skills include writing, economics, mathematics (understanding programming helps)
4) Producers: skills include project management, scheduling, budgeting, and team management
But, mostly, if you love games, you should start making them. It doesn't matter if you program them on a computer or make them out of paper, start building something. This will help you understand what you love to do and will naturally lead you to the right skills to study for your personal interests. Also, understand that modern games -- especially video games -- aren't built by individuals. They take teams of people multiple years to complete -- at least, the AAA console and PC titles. So don't get discouraged if your games don't look and feel like Overwatch or Divinity: Original Sin.
