Quantum Break. Its ending most certainly was teasing a sequel. Unfortunately, Microsoft was never willing to sell the rights to the IP to Remedy.

Bushido Blade.

All fighting games are boring in comparison to the first of this franchise. Could literally remaster the first one and change nothing but the graphics and it would be a hit.

Treasures of the deep as well. That one needs a controller scheme rework for sure.

Bloody Roar. The rights are held by Konami, so there's practically no chance of it happening.

Days Gone 2 (not gonna happen though).

I'm excited to see the new jet set radio and crazy taxi.

Not because I'm at all interested in playing them but because I want to see the absolute shitshow they will both assuredly release as.

Batman Arkham

Pikmin 5

Funny one: Psi-Ops

Hi-Fi Rush.

I was so distraught when the studio was closed despite selling extremely well and working on a sequel. I am beyond excited now that the studio has been picked up by ~~Zenimax~~ Krafton. There's no confirmation, but you don't go from planning a sequel to a breakout hit, to being closed down, to being picked up by another parent company just to scrap said sequel.

EDIT: Fixed the company buy-up. Forgot the order of things.

Vampire masquerade bloodlines...yes I know they're working on one, but they've been working on it for years now and it's been bouncing around to different devs, which just seem to either try and make it something else or deviate from the original completely.

Kingdoms of Amalur. Though I'm just happy the new DLC was decent after such an odd history getting there. I doubt a faithful sequel can be done from scratch.

Sundered. I would love to see the equivalent of Rogue Legacy 2 for that game, where the sequel completely supplants the original while expanding upon the storytelling and lore.

Kenshi 2, but I just want a remastered version that makes it more playable.

It's long dead thanks to kinect, but another Sonic Riders game would be amazing.

Absolutely loved Zero Gravity and never played the others (because I didn't know they were part of a series), but I would absolutely love even just a combination of the air fuel like mechanic of the original combined with the gravity meteor ring things. No clue what the kinect version would bring since I've never heard that good of things about it besides the main theme being great, so maybe exclude elements from that title.

Grim Dawn. We're getting a new expansion sometime, and I'm fucking hyped, but I want to see more of Cairn. I want to see even more regions, I want to see time pass and how this world tries to recover, how far the gods have truly fallen, how far the Witch Gods may go now that things have broken so deeply.

Not true sequels, but Alabaster Dawn from the Crosscode Devs, and Psycho Patrol R from the Cruelty Squad Dev! Both are some of my favorite games, so I can't wait to see the "successor" games come out!

Okami just had its sequel teased after about ~~15~~ 20 years. I’m excited to see what they do with it.

edit: 2006 was not 20 years ago! :(

A new redout game that is capable of mantaining a community would be great.

Baldur's Gate 4, but that's unlikely to happen at this point.

Anachronox, but that’s never going to happen :(

That game ended on such a cliffhanger.
