It IS great time to be a PC gamer, but not because of PC games. It's console games ported to PC, that run at higher resolution and frame rates, that make it great.
Honestly, I miss the good old days. I felt like in the early to mid 90s they were still making AAA PC games. Now they only develop major titles for consoles, it seems, which is fine. It just makes me less inclined to upgrade my PC. Obviously 4K is better but, thanks to the common practice of upscaling, 1080 is still perfectly acceptable.
I'm honestly enjoying the games on PC like XCOM 2, and for years I;ve njoyed TF2, Planetside 2, Starbound, How to Survive 1-2, Project Zomboid, Stardew Valley, Starcraft II, Diablo III, Heroes of the Storm and a load more that aren't direct console ports and aren't all about realistic visuals. I don't think it's made great only because of console ports (it's like saying PC is only great thanks to consoles which isn't really what the thread is about).
I'm not sure what kind of AAA games you are talking about because so far I'm still seeing those happening on PC, just not the same way you think they are.
