This game is entertaining, but overall not a game worth spending money. It’s fun to rent, but I basically unlocked all the games and extras in less than a day. If you like pet games, then this is probably your game and you should rent it.
On the other hand if you like hard survival like zombie games, then this is not what you’re looking for. You have to level up your zombie about 10 times before you’re even able to play the second game that allows you to earn more money. It takes a lot of leveling up to actually get to the fun stuff, yet… it doesn’t take all that long to get there.
So overall if you’re a pet game lover, and you like the occasional adding of a zombie theme. Then yes, this is the game to rent. But if you like things like Resident Evil, or Plants vs Zombies… don’t rent this game.
