What video game have you played the most, that you think is garbage and no one else should ever play?
I have played Eve Online so many hours, and it's a bad game. Don't do it. you will spend hundreds of hours dreaming about the cool thing you'll do later, but for 99% of players the cool thing will never happen. You will be part of the one percent's cool thing.
When I was about 13, I started playing this MMO called Nexus TK. I have spent what I'm sure is thousands of hours playing it. I kicked the habit for a whule, but recently re-registered to see what was going on. It's a slow responding 2D "action" MMO, and the decline in players turned it into a weird niche clique where newcomers are basically not welcome. But it's still up and running 25 years later.
