What to start with if I haven’t gamed in over 20 years?

I haven’t played in over 20 years, since I was a kid. I have never had a console. At that time I played computer games like Zoo Tycoon, The Sims, Rayman, The Incredible Machine, Black and White, Sim City and the one where you build a theme park, and Worms. A bit of pokemon on friend’s gameboy color. Thinking of getting back into it, even a bit, now, feels overwhelming, I don’t know where or with what to start. I cannot afford to buy a gaming PC or any console, I just have a regular reasonable laptop. Any recommendations for games I should check out?
