I’m stuck between two 

- Street Fighter x Yakuza 6 or 0

just because of how good the story telling is in 6, would be really cool to see a mashup of the two especially in the fighting scenes

 - Deep rock galactic x No mans sky 

I’d combine the main gameplay from deep rock and the exploration from No Man’s Sky 

Imagine being able to explore hundreds of planets with your fellow dwarves lol

   In my opinion, an awesome mix of games would be Metal Gear Solid (ill just say Phantom Pain since it's the latest) combined with Silent Hill. I’m aware that Hideo Kojima was working on the Silent Hills game, but I promise that is not reasoning, as the PT playable demo was nowhere near this combination. I think a deep psychological horror game combined with the stealth mechanics of Metal Gear Solid would be incredible.

Ui

probably Off Topics but one of the best all in one combination games was Grand Theft Auto Series.

and Grand Theft Auto VI Trailer just Drop around 5 hours ago, Coming 2025.

RIP :P

Thought it’ll be released next year :)

better late than Cyberpunk 2077
