The game's story set-up in the Nintendo 64 and PC versions is that the wizard's accident is caused due to him mixing the wrong potions causing him to turn to stone, however in the PlayStation intro the incident is instead depicted as being deliberately brought about by the glove that becomes the game's villain, Cross-Stitch. The manual for the PlayStation release retains the incident as being an accident and not deliberate as seen in the other versions.

There almost was a sequel to the game called Glover 2, and was planned to be released for the N64, PS1, and the Dreamcast. According to Jason Steele, a programmer for Interactive Studios, he revealed on his blog that someone overestimated the amount of cartridges needed for the N64 release, resulting in the sequel being cancelled. The game, according to Steele, was 80-85% complete when it was cancelled.

“…as far as we were told, Glover 2 had been canned because of Glover 1. Now this seems strange, because the first Glover has sold fairly well for a non-Nintendo N64 title. And it was on the back of those sales that Glover 2 had been given the go-ahead at Hasbro in the first place.

But Hasbro had messed up. They had screwed the pooch big time. You see, when ordering the carts for the first game, the standard production run was something like 150,000 units. And this is what the management at ISL had advised Hasbro to order – because the N64 wasn’t really fairing that well compared to the PS1 at the time and non Nintendo titles tended to sell poorly. They thought that Glover was a good game in its own right, and a moderate 3rd party success would sell around 150,000 units. And that is exactly what happened. Hence the go ahead for the sequel.

So Glover was a money maker for Hasbro, right? Right? Nuh-uh. As it happened, Nintendo had a special on N64 carts at the time the game was being schedule for production. Some bright spark at Hasbro thought it would just be absolutely SUPER to order double the normal amount – so they put in an order 300,000 units at a slightly reduced cost.

The problem was that none of the retailers wanted to take that stock off Hasbro’s hands. The game had been moderately successful, but the demand just wasn’t there. And thus Hasbro was left with 150,000 or so copies of Glover for the N64 that nobody wanted. That’s something like half-a-million dollars worth of stock that they can’t shift. And with Hasbro Interactive not being in the best of financial shape Glover became a dirty word around the company, as it became apparent over the course of Glover 2 development that they were stuck with all those carts.

Of course, the blame was put on the game and brand itself rather than the idiot who ordered the extra 150,000 carts from Nintendo. And that ladies and gentlemen, is why Glover 2 had been cancelled.”

Before Jason Steele made his statement on his blog, someone leaked the ROM for the game on October 2011.
