Maybe proving/disproving the Earth is flat That would be great!

Of cource it planar. Is you see any FPS around where it not a planar? It just some kind of optimisation that allow to use a same G vector for any object instead to recalculate it for each object every frame that involve a expensive vector normalisation operation. ?

To further continue on question what happens when your games fail (or generally you fail business side miserably) - I will post a real world example - Telltale Games.

The studio recently terminated majority of the positions, and seems to be closing up.

My advice to people is always the same. Never give up your day job, unless the project you are working on starts to be successful to the point that you can't continue with your regular job. That is rare for anyone.

I am a developer by day. It's not in games. The subject matter is probably quite boring but it brings in a good steady income for the family.

To answer one of your questions: about getting the time and why program when you program all day, for me the answer comes from the fact that I rarely watch TV. Maybe occasionally. It certainly helps to not own Netflix or anything like it.

And when you have a couple of night time game projects on the boil, and are loving the progress you make, there's a nice kick of endorphins.

Make learning game development a hobby to enjoy. Have a job you enjoy. Watch less TV. See where things go.

When your developing a game, it's all to easy to fall into an obsessive or workaholic frame of mind.  

It's easy to convince yourself that once it's out, you wil make up for all the sacrifices in respect and money. 

Too many people these days are categorizing too many things as addictions. 

If it doesn't work out, it's an addiction, if it does, your a dedicated success. 

It's about balance, just make sure your balancing your life, and sacrificing for long term goals,not short term hits. 

And even if it fails, it still counts as experience. People learn more from failure than success.
