I was interested in this game because it was featured in the first game magazine I ever got (a month before I started subscribing to Nintendo Power) was an issue of GamePro in December 1990, the one with Bart, Marge, and Homer Simpson on the cover.
At the time they had a series of comics starring a guy named GamePro, who travelled through games (kind of like Captain N, or a more serious and action-packed version of Nintendo Power's Howard & Nester, I suppose). In that particular issue he was in The Adventures of Rad Gravity. I can't remember what happened, though it might have been the stage in the game where Rad has to save that cycloptic computer that was captured and put on a conveyor belt towards the incinerator or whatever that is. And when GamePro left that game at the end of that episode, he was headed into Michael Jackson's Moonwalker for next month's adventure, I believe.
Last time I looked, there was not a Wikipedia article for this GamePro character, and it's probably hard to find on Google. That's a problem when a character shares his namesake with the magazine itself.
I wouldn't mind looking at the full compilations of the comics again (I know that official collected volumes exist), even if they probably would be pretty cheesy. I remember that there was a beginning and an end and enough of a story arc, too, unlike Howard & Nester, even if most of the comics in between were throwaway episodes. Though I remember thinking it was a big deal when the cybernetic bad guy (I think his name was "Stalker" though I could be wrong) who was pursuing GamePro got some kind of upgrade...basically made to look cooler, at least I thought so.
