Back in the day when I was a student, I travelled for almost 3 hours by train multiple times per month... I played Rollercoaster Tycoon 2 on my laptop all the way. Surprisingly, even while wearing large headphones, I connected with many people who saw me playing a game that they loved.

RCT2 remains a brilliant game today. The OpenRCT2 project is very well maintained and I can highly recommend it if you want to play it on your modern computer.
