True Fantasy Live Online looked like it would have been amazing.

Silent Hills, it would have been interesting to see what Kojima and Guillermo del Toro would have created... but unfortunately.

Also: Starcraft Ghost, the original Fallout 3, Fez 2, Mother 3 on N64, Legacy of Kain the sixth game (not Dead Sun/Nosgoth), the original Duke Nukem Forever, and probably a bunch of others that I can't remember right now.

I wish we could have gotten R6:Patriots.

i dont understand why nobody has mentioned nosgoth yet. i regularly think about and miss this game so much!!!

Probably the Hardsuit Labs version of Bloodlines 2. Playing as a thin-blood and getting to diablerie would have been really fun.

LittleBigPlanet, can't wait for Restitched. At least private servers exist and I can emulate LBP2 on my PC

Technically it was never released, but I was invited to a closed alpha (or beta?) for a game called Chroma, by Harmonix, the OG Guitar Hero people. It was a lot of fun and I'm still sad that it was canceled...

Obligatory “fuck Notch” but I really liked the idea of 0x10c when it was announced.

Blacklight Retribution was pretty great. I played quite early in its lifespan, during an event which gave me a special nameplate - nothing more than a participation trophy, and at the time, loads of people used it.

Signed in a few years later to.play a few rounds, and some guy begged me to let them use my account because of that now-rare nameplate.

(I also had an extremely cool helmet and some seriously powerful guns I got for free in that game's equivalent of a lootbox)

Beyond Good and Evil 2.

I’m not even mad that we didn’t get the multiplanetary open world new-tech live-experience cooperative second coming. I’m mad we didn’t even get a simple, short singleplayer experience living off of the charm of the first one.

Chrono Break

City of Heroes, everything by Atari Games, the Wizardry series, the Ultima series, many others. I'm old, and I remember some of the games, and developers, we've lost.

The Culling

Before the devs ruined it by throwing away the movement and combat system.

Wasn't canceled but they might as well have because they lost 99% of their playerbase from that one change in Beta.

Marvel Heroes. Hopefully the private servers being worked on will be in a playable state someday.

Reset, a puzzle sci-fi game some little Finnish studio was working on.

Honestly, I was really looking forward to EverQuest Next. The idea sounded promising before it was cancelled.

TimeSplitters 4. If they'd have stopped baiting us with teaser art and promises of someone new buying the bones of Free Radical every few years then it wouldn't hurt so much.

Loadout. It was a casual PvP (and later PvE) game where you can make your own weapons with wacky combos. It was a bit pay-to-win, but I thought it was very fun. The game crashed and burned because the studio wasn't sure what they wanted to do with it and kept ignoring fans.

I think the PvE spinoff never came out of beta. I was looking forward to it.

The StarCraft FPS.

I'm still mad about it.
