Hamtaro: Ham-Hams Unite review. Classic Game Room presents a CGR Undertow review of Hamtaro: Ham-Hams Unite for Game Boy Color developed by Pax Softnica and published by Nintendo. HAMHA! Enter a world where hamsters speak another language... well, where hamsters speak any language, truth be told... and act like a linguistic anthropologist as you study dozens of terms in Ham-Chat and use them to assemble your team of Ham-Hams at the clubhouse for reasons that will be explained later. It's a weird mix of text-based adventure and adorable cartoon cash-in, but one that features plenty of environmental interaction and growing complexity as your vocabulary develops. This video review features video gameplay footage of Hamtaro: Ham-Hams Unite for Game Boy Color and audio commentary from Classic Game Room's TJ.
