Hamster Paradise 4 review. Classic Game Room presents a CGR Undertow import review of Hamster Paradise 4 for Game Boy Color developed by Digital Kids and published by Atlus. Hamster Paradise 4 asks the question, "So, what about TWO HAMSTERS?" The majority of the hamster-rearing action from the first two iterations returns, along with some new minigames... but the biggest difference is in the inclusion of a second hamster and their various hamster-interactions, formerly available only in multiplayer. The hamster professor and his assistant return as well, and introduce... well, not much else. Some features have been stripped back, to make room for that second hamster. This video review features video gameplay footage of Hamster Paradise 4 for Game Boy Color and audio commentary from Classic Game Room's TJ.
