For me, the best PC game ever created is a weird, unpolished and quixotic affair called
Kenshi.
For those of you who have never heard of it, it's classified as a "swordpunk" isometric game that's set on a dystopian alien world. It has no plot. It has no quests. And none of the characters that are in it care if you live or die other than your own. You can play it as a lone wanderer battling against a vast and exceedingly harsh world that will do its absolute best to separate you from your limbs, enslave you and torture you to death, or you can build a faction full of unique individuals that work as a team to overcome the almost insurmountable challenges the game throws at you. There are no restrictions on your conduct, but there are consequences for every action you take, and there is no right way to play it. You can buy up property and open a sake bar, or go hunting for ancient and mysterious monsters, or unlock ancient technological secrets from the gameworld's rich and brutal past. You can become a petty thug living in the swamps or overthrow an emperor and supplant him.
What's really amazing is that all of this was done, for the most part, by just one developer named Chris Hunt. Chris worked as a security guard while making the game. It took him years to create all of Kenshi's unique assets and make them come to life, but in the end, he produced a game that was both brilliantly "empty" and somehow so full of things to do and stories to write for ourselves that it overflows almost from the first moment you're thrown into it.
If you haven't played Kenshi, I can't recommend it enough. At first, you wonder what the hell this mess of terrible, outdated textures is trying to be. A few hours later, you'll wonder where the last few hours went. And when you realize that the game never really ends, you might get as hooked on it as I did. I put Kenshi in the same sphere as Torment and New Vegas, and somehow it elevates itself above those games for me. If you haven't played Kenshi, you really should. Real GOAT material.
