The cell stage of Spore is by far the most simple of the games stages but to consider it a tutorial level or something truly simple is to over look much of what this game is. Spore is not a game that is designed to challenge a person in the way that most video games do but instead it is designed to help you create something rather than simply trying to destroy.
You will begin the stage by choosing whether you want to be a herbivore or a carnivore. This will in some ways define you throughout the game, though you can change this to some extent as you advance and even become an omnivore but it is still worth considering. Do you want to befriend everyone or simply wipe them out.
From this point on you’ll be mostly focusing on getting food. Food comes in the form of green plants and red flesh. You’ll focus on whatever type it is that you are able to eat, at least until you get to the point where you can become an omnivore.
As you eat you’ll get DNA points. These allow you to add more to your creature, spikes, fins, jets, electricity, poison and eyes just to name a few. These will allow you to either kill prey or defend yourself, as well as move faster, turn better and see.
Do not underestimate the value of speed in this level. Your weapons are only as useful as your ability to outmaneuver your opponent creatures. Also there is no real loss to dying beyond the fact that the game keeps track of how many times you do.
As you eat you will also grow. This means that if you find food that is too big for you to eat currently you might be able to do so once you get bigger. It also allows you to get some revenge on those creatures which harassed you while you were tiny.
One major thing to keep in mind is that each stage gives you one trait. In this stage it is the type of food you’ll eat. If you don’t want to be a herbivore but an omnivore try to keep the amount about even and even then it isn’t always easy.
This is the simplest part of the spore game and you’ll play through it in about an hour, but it is a lot of fun and without it the other parts of the game simply mean less.
