If I look at that list, I think that the PC gaming world is in one hell of a sorry state.
On that list of twenty titles I see only one that's fairly original, and that's Stardew Valley.
Fifteen titles are are direct sequels, Inside is 'just another platformer', Overwatch is Team Fortress in all but name, and The Division is a copy of about a hundred titles that by now are indistinguishable from each other.
And Stellaris? Just another friggin' forrecks game. Sigh.
What a carpy state of affairs!
I could name about ten to twelve indie titles that should be on that list for creativity and longevity alone, but this lot as contenders for THE top games for a whole year?
Sorry, but that's just not good enough for the whole gaming industry. It reeks of laziness, money grabbing, and pee-taking, it reeks of economic fear of producing a flop. This is not much more than an accountant's dream list.
