I am part of a very, very small minority of players who enjoy FPS shooters with bots...and without any interaction with any human players. I just don't like online play. I play Souls games offline, just to avoid people.
But I spent a TON of money as a teenager on games like Unreal Tournament and Quake III, UT2k3, 2k4, Team Arena, you name it. Because I just like playing with bots. I absolutely love team based FPSes, but...I just like playing alone with bots. Not because it's easy. I make sure the bots are hard as hell.
It's sad to see bots, and that kind of play being marginalized, if not outright ignored. Back then you could enjoy every mode, map and weapon of UT and Q3A without connecting online. I'm not asking for a campaign. I'm asking to be able to play these games by myself.
I could play TF2 alone. Unlock achievements. Enjoy the gameplay without the stress of competition. I sure as fuck wish I could do that with Overwatch. But I can't.
