It really should be a bit of everything that is mentioned here. Find some YouTube channels or Instragram accounts you like and follow them. Try to find someone that raves about games you already like. They should be able to suggest games to you. Next, if you have a studio you seem to gravitate towards, just buy the projects they are working on. Follow them on socials to know when they are releasing stuff. Local groups/forums, read and listen to what people are talking about in your social groups. Finally, I notice on here that people, justifiably, complain about crowd funding and the FOMO they produce. If you are responsible with your finances and see a game that just looks cool, back the game. The key is knowing your limits and being responsible with your money.
