My guess is that it is search engine optimisation. Matching words in the title might give a higher rank than words only found in the description.
I suspect that the "Puzzle Quest" brand alone isn't quite as well known these days. It's been almost a decade since the last main series Puzzle Quest game from Infinite Interactive, and these days people may only know them from the mobile versions that were filled with microtransactions.
In contrast, there's probably more people searching for "marvel rpg" or "hero rpg" these days.
