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.
Looking at my Steam, the game with the highest number of hours played, of which I would currently say unambiguously that you should avoid it, looks to be War Thunder. Among the reasons I'd tell you to stay away from it:
It's a grindfest starting very early on.
It's far too easy to lose as a result of what can reasonably be called bad luck.
Unless you specialise, or throw real money at it, the fun, high-tech stuff is probably thousands of hours into the future.
There's content gated behind "if you were not around when this was regular stuff, you will never get it"
It calls itself an MMO, while there's nothing MMO about it. It's all instanced battles, with little to no world continuity as you progress.
