Metal Gear Solid 2 is a game in which the central gameplay revolves around espionage. The player is given a choice of different weapons to choose from. Each weapon has its advantages and disadvantages. For example, the tranquilizer gun is useful for quietly taking down enemies without being too loud or causing all enemies to go on alert from finding a dead soldier. However, the tranquilizer gun is useless in taking down robotic enemies. The rocket launcher, on the other hand, is good at destroying things quickly, but it is really easy for enemies to notice and go after you. All enemies have a field of vision and a range in which they can notice suspicious noises. It is usually a good idea for the player to sneak around enemies unnoticed by either avoiding their field of senses or hiding in unsuspicious places such as lockers or cardboard boxes.
Beatmania is a game in which the player uses a controller similar to a turntable. It is a rhythm game like Rockband or DDR. The player picks a song and a difficulty level. When the song they picked starts playing, lines fall from the top of the screen and when they reach the beat line, the player has to hit the corresponding keys. If the player’s accuracy is high enough, they can make it through the song and pass, otherwise, the song ends prematurely and the player fails.
These games are similar in that they both can take input from one player by a controller. For Metal Gear, it is the classic PS2 controller. For Beatmania, it is a controller that resembles a turntable. They both have winning and losing conditions - there is a goal to fulfill, and if it is not, the player gets a game over. For Metal Gear, the goal is to continue along the narrative path, and you lose if your health drops below zero or you’re seen by certain enemies. For Beatmania, the goal is to pass a song, by hitting enough notes correctly, and you lose if you can’t hit enough. Both games have an aspect of collection. In Metal Gear, the player collects ammunition, and weapons. In Beatmania, the player collects points depending on their accuracy. Each game has Title screens, and menus. There is conflict in both. For Metal Gear, the conflict is that between the player and the enemy - who has the advantage over who as well as figuring out the best way to avoid enemies without being seen. For Beatmania, the conflict is in the players ability to hit the correct notes at the right time. In Metal Gear, the player is bound within the set levels, otherwise the player will fall into the ocean and die. In Beatmania, the player is bound within menu screens and the play screen of falling lines. The outcomes in Metal Gear further the player along in the story while in Beatmania, the player achieves a top score.
