Instead of claiming territory on a playfield (like in that Taito hit), Critter Round-Up has your unnamed protagonist fencing in various animals without mixing species, all the while avoiding contact with said critters. The ability to produce fences at a rapid pace hardly tops my wish list of fantastical videogame powers, but Critter Round-Up parlays that odd premise into a pretty traditional arcade-style experience, with power-ups, a cumulative score, and a limited number of lives."
