Thats what No Man's Sky is for me.

J-rpg with a setting and atmospehere similar to what you'd see in a H.P. Lovecraft story and action battle system similar to the one in Tales of games.

Transformers RTS.

One Piece Open world sandbox.

Elder scrolls world-building sim.

Terminator RTS.

Warcraft sims.

Dark Cloud 3 and Dragon's Dogma 2

Legend of Dragoon 2
KOTOR 3
Jade Empire 2
Dragon's Dogma 2
Battle for Middle Earth 3
And a whole lot of random ideas for games I have floating around my head lol

Xenogears 2, Xenosaga 4,5, and 6, Xenoblade X-2. For starters. Get to work Takahashi!

I want to play the original RE4 before it was canned and replaced by an entirely new IP and branded as RE4. I haven't gotten to play a new RE game since RE CV and it sucks because that's my favorite survival horror franchise of all time.

Some good choices in this thread. I have a few game ideas on my own (which are secret), but I want these games made by today's devs on PS4:
-Berserk by FromSoft/PlatinumGames collab
-3D Castlevania-like with glorious art style from Ayami Kojima by FromSoft
-Fist of the North Star by PlatinmGames
-Star Wars action game by PlatinumGames
-Star Wars RPG by BioWare
-A dark themed JRPG like Atlus' PS2 output with the previous art director(Kaneko)
-H. R. Giger 3D action game, but can't decide by which dev : either Platinum, From, Creative Assembly or Naughty Dog

Lots of calls for KotOR3. Good, f* the MMO! >:(

I forgot something on my original post though. Ever since Galactic Battlegrounds, Age of Mythology and Warcraft 3, I've been wanting a Star Trek RTS taking the best things of those games. With Starfleet, Klingons, Romulans, the Borg and whatever as playable races. Throw in a little Empire at War spacebattles, and it could be cool.

An amiibo game where I can form a gang consisting of Shulk, Cloud Strife, and Marie, while making fun of casual kids who only use Mario.
