Is it worth buying ETS1? I really wanted to because my PC and laptop can't run ATS or ETS2.

I really wanted a cheap game to pass the time. I don't care about ugly graphics, I just want to play and have some fun. I played a bit of the ATS and ETS2 demos (at 15 fps), and I liked ETS, so I wanted to know if ETS1 is worth playing for hours and hours.
