Most games you eventually get tired of at some point. Whether it doesn't have enough content to keep you interested or that it's just the same thing over and over. And after a while a game will lose the appeal it once had when you first played it. However Starcraft transcends this in a few key ways.

First of all is the evolution of the game. As people play Starcraft and hone their skills, new strategies are developed. New threats must be accounted for. Being able to determine what your opponent is planning to do is a skill in and of itself and is vital at higher levels of play as you may find yourself ill prepared for what your opponent has up their sleeve.

Secondly is the depth of the game. Over time you will learn the most efficient way to play as your race of choice and make the most use of it's respective strengths. Your perspective of Starcraft will change as you play it. Much like as in other games such as Team Fortress 2, you will start to notice new things as you improve. In Team Fortress 2 you will start to recognize amoungst the various sounds of battle when a spy has uncloaked near you, or you will see a weak point in the other team's defense and be able to exploit it with the appropriate class. In Starcraft it goes much deeper. When you first play the game you won't know what a certain composition of units means. You won't know where you are being hit when a nuclear launch is detected. However as you continue to play the game these things become obvious to you. You will start to see things as you never did before. Seeing a lot of static defense in the enemy's base will mean so much more to you than when you first started to play and it only looked difficult to attack. If you spot certain tells in time you will know what you need to in order to counter your opponent's strategy. In this way the game's entertainment value rises as you continue to play it.

Third is the custom content created by the Starcraft community. Besides countless maps are varying game modes available to play. Be it tower defense, space battles, the ever popular Phantom Mode, or even Mafia, there is something for everyone. And new ones are always being developed. Take for example Phantom Mode. This is similar to the main game in it's mode of play, however it is much different gameplay wise. There are a few options to choose from at the start, but typically there are eight players total. Two paladins, four slayers, and two phantoms. The slayers are normal players allied with the paladins and they get a bounty for killing an enemy. Paladins get a regular income of resources that diminishes as slayers are killed. Phantoms get an income of resources that increases over time as well as extra supply over time as well. Supply is what limits the amount of units you can make. Nobody knows who anybody else is so the slayers and paladins must determine who the phantoms are before they grow too powerful for anybody to defeat. Deception is a large part of the game as a clever phantom will turn his enemies against eachother.

These are just a few aspects of the game that make it entertaining and keep it's players coming back for more.
