 While working on the game, they found that developing game art for "Gex" was far harder than it had been with 16-bit video games, as the expanded 32-bit memory in combination with the storage capabilities of a compact disc meant that far more art could be made.With two artists working on the game's assets, a single in-game level took around two months to complete.Because Crystal Dynamics' two other 3DO games being developed at the time, "Crash N Burn" and "Total Eclipse", only required a small number of artists, Panasonic was hesitant in hiring additional artists to the game's development team, presuming it to be unnecessary.
