The video game market fascinates me. Every quarter of a year, there are what feels like hundreds of video games that come out. It's baffling and frustrating the amount of video games that come out but tend to party make a 'splash' in the video game industry market. Especially those who take creative risks and don't get much coverage. Hence why I asked the question. =)
I'll caveat this with I think a lot of games mix genres so you might even want to narrow it down a bit. (For example Ghost Recon: Wildlands is a coop, open world, action, adventure, stealth, and a modern military third person shooter.)
But I'll try and give some more noticablely mixed ones:
Doki Doki Literature Club (Don't look anything up just play it, don't worry if it doesn't seem like something you'd usually enjoy)
Natural Selection 2 (Space Marines vs aliens pvp fps with commanders playing a rts match)
Superhot (A fps with evading bullets offering a puzzle-like element)
I love Natural Selection 2! Really glad that an FPS-RTS game has been able to make it and stay around. I still hold out hope for another FPS-RTS game to make it big. There have been a couple/several that have made it to market but most of them are not finished or died in early access development sadly.
One other game that I think a lot of people overlooked as being one was Battlefield 4 + Hardline. Which had their own commander modes. Last I checked 4 still had community servers running, might even have more players that NS2 still.
