Half-Life 2: Episode Three.
IIRC, it might have been cancelled as the PS1 was going to be released around the same time and Sony didn't want to release a game on a competitor's platform.
Fun fact about Glover 2, the reason why the game was cancelled was because someone at Hasbro ordered 300,000 N64 carts for the first game instead of 150,000, because Nintendo was offering a deal on bulk purchases of carts. As a result stores wouldn't take the extra stock of Glover carts, causing Hasbro to lose money on the game, hence the cancellation of the sequel. A decent amount of work had been oured into the game before its cancellation:we'd be living in a utopian society if the world had gotten Glover 2
According to Wikipedia they stopped development after a 2011 Earthquake in Japan. In 2012 Hudson Soft ultimately merged with Konami and ceased to be. So it's safe to assume that they were just so strapped for cash that they just didn't have the capital to finish up Bonk. Pretty sad.Dead Phoenix, Nintendo and Capcom make a deal called the Capcom 5, which were 5 games which would come to the gamecube however one of those games never came out and the others all made their way to other consoles.
Magical Ninjya: Jiraiya Kenzan, another Capcom game this time for the PS2
Crash Landed, planned reboot for the ps3 and 360
Snake Plissken’s Escape, was to be done by the Dead to Rights devs and it seems both Kurt Russell and John Carpenter were involved to some levels
Cosmic Walker, only 6 seconds were shown but still looked neat and was done by Kouji Okada one founders of Atlus and creators of SMT
Saints Row: Undercover, was a psp game then moved over to 3ds only to never come out
Gremlins ps2, was a nearly done wii game but that was a shitty party game and can been found online if anyone really wanted to play it
Road Trip, a zombie game
Bonk: Brink of Extinction, seemed nearly done so no idea why it was shit canned
