So here is my basic advice:
Do what you want to do and will bring you joy and meaning.
BUT realize:
1. It will take more money than you think it will.
2. It will take more time than you think it will.
3. It will become more of a burden on you than you can possibly imagine right now until it is entirely financially self sufficient (years).
4. You will constantly be pressed to spend more time doing other things that actually make money other than being at your arcade.
5. Your family will wonder why Dad can’t come along for (insert event).
6. You will constantly be dealing with repairs, expensive repairs that will additionally suck your time away and cause you headaches because you don’t want to be THAT arcade that has half the games down.
If ALL OF THAT doesn’t scare you off, then yes you should run an arcade. I still run an arcade (just barely) even though I am a surgeon, run a full time research lab, run a startup medical imaging company, and have a family I want to spend lots of time with. It’s either a calling or it’s not. If it’s not a calling and you can’t float the cash outlay to do it, don’t do it. Just remember there is an opportunity and financial cost to everything you do and at this point you commodity likely in shortest supply is your time. Just be sure that’s how you want to truly spend your time
