Hey dude I am not a hardcore gamer but it is definitely a hobby. However, unlike some people here, I have no interest in railing on you. Instead, here's some genuine advice to think about:
You're asking a difficult question, as few jobs pay decent and are also easy and low stress (and, I might add, something you'd enjoy).
The best advice I've heard on picking a job is to 1) figure out what you like doing (this is not always easy), 2) pick which of those you are good at, and 3) pick the ones you like and are good at that promise decent pay. If you notice, everything starts with figuring out what you like doing. You will be hating life if you hate your job--so first figure out what you like doing.
That being said, here are some more thoughts.
You didn't indicate if you want to work indoors or if you are willing to do manual work, so I'll talk about both.
If you work for the state government or a bank, you are almost guaranteed to be working 9-5 with little or no overtime. Government jobs are also steady employment and generally low stress. A job in the $30-35k range (adequate for a single guy living alone) is not too difficult to come by, but at this range you will be driving used cars and might be renting a place instead of owning a home.
One way to quickly get into a decent job is to go to trade school. Welders, machinists, A/C installers (HVAC), electricians, etc., make decent money anywhere in the country. On occasion you will have to work late but you will get paid for that. The trades are a solid industry. I know a guy who made 20k every summer just pressure washing peoples driveways, siding, etc., and he started with a rented pressure washer. Guys who do landscaping, etc., also make decent money once you're beyond the lawn-mowing phase.
There are some jobs you can do from home, but not many. Most of them involve talking on the phone, and some of them involve talking to perverts on the phone--not a lot of stress and decent pay, but what a rough way to make a living.
I would encourage you to pick up the book Millionaire Next Door, or to read the book Over the Top by Ziglar.
You can make good money doing just about anything if you are willing to start your own business. I work for myself. I don't make tons of money, but have a decent living (getting better), I have my own place and car, and I can start work at 6 am or 11 am. Not always low stress but I'm not tearing my hair out.
Ultimately, pay is reflective of your value to the market. If what you are doing is easy and low stress, anyone can do it, so it tends to pay less. Your pay will relate to how much work you are willing to do--if you want to lean on a mop, you won't be worth as much as the guy who is saving lives. My job is hard to do and occasionally is stressful (not overwhelming) but that's why there is good potential for money. Maybe you'd be willing to work fast if the work was easy? Maybe you'd be willing to work hard if it was for short bursts? I wish I could tell from your question so I could give more tailored advice.
I hope that this helps. I'll say that when I worked for the government, it was the easiest job I've ever had and I never would have been fired (I left). Decent money with good benefits and you never work late. My position didn't allow me to really do much, though, so my job satisfaction was low. I HIGHLY recommend picking something you'll love doing--if you love it, you can figure out ways to lower the stress or make it easier, or make more money from it. If you have all the other factors besides liking it, though, I think you'll just have a 'job', that you hate, like many many others.
Drop me a note if I can be of any help. Good luck dude.
