Yea, I remember those days too. The best game out there was a text based Star Trek game called Space Wars because of possible copyright infringement. It took about one minute to make a single move or fire a torpeedo. If you warped into a sector with more than two Klingon ships, you’d better use phasers and knock them out in a single salvo or you may not get a second chance.
When I went off to collage I got my first taste of computer-to-computer stuff with a 1200 Baud modem connection on a teletype machine.
A few years later I bought my first PC with a 386SX processor (16MHz), 1 Meg of RAM and a 56k baud modem. I thought I was in heaven compared to the 2MHz machines I was running a year earlier. I remember that machine cost me over $1000, & I wouldn’t need to spend more than that now for a contemporary machine. Heck, I wonder how powerful my cell phone is?
