Harry Potter and the Philosopher's Stone (released in the United States as Harry Potter and the Sorcerer's Stone) is an action-adventure video game with platform elements published by Electronic Arts. It is based on J.K Rowling's 1997 novel of the same name and the 2001 film adaptation. Philosopher's Stone was initially developed for the Game Boy Advance, Game Boy Color, Microsoft Windows and PlayStation in November 2001, and was re-made two years later for the GameCube, PlayStation 2 and Xbox in December 2003. The story follows protagonist Harry Potter, who, after discovering he is a wizard, is sent to Hogwarts School of Witchcraft and Wizardry where he makes friends and receives magical training, and along with his friends stop Lord Voldemort from returning to power. The game received mixed reviews. Critics commented on the game's accessible gameplay and its unimpressive graphics (2003 versions) while others said the game's license would be the only thing to draw in fans. In the PC versions, the game is played like a third-person action and puzzle game. The story follows a linear progression, separated into levels with a specific end goal. Spells are learned progressively via lesson levels, and unlock increasingly complex puzzles. The spells featured are as follows: The Flipendo Jinx, which can be used to stun enemies and push objects around; The Alohomora Charm, which unlocks doors and chests; Wingardium Leviosa, which can levitate objects; Lumos, which causes platforms of light to appear; Incendio, which can disable aggressive plants. The storyline follows Harry through the main elements of the book's plot, including rescuing Hagrid's dragon Norbert, advancing through the various protections around the Philosopher's Stone, and eventually defeating Lord Voldemort. There are also several levels in which Harry can fly on a broomstick and play Quidditch - this gameplay can also be independently accessed through the start menu.

First released on Microsoft Windows on 21 March 2001. It had been in development since 1996 and had videos showing its early gameplay in 2000. The First Encounter was originally developed by Croteam as a demonstrator for their engine and the reason why some countries saw its initial release priced at less than half the price of other games in the genre. This game was followed by a sequel, Serious Sam: The Second Encounter released 11 months later. Serious Sam: The First Encounter's gameplay consists almost entirely of the player attempting to defeat dozens of enemies at a time in wide-open arena-like areas and thus is relatively simple. The game's story establishes the reasons and methods for how the player travels from chapter to chapter through the game's menu system called NETRISCA. Enemies spawn frequently and attack in large waves from across the game map, and the player is intended to dodge their projectiles and charges by jumping and strafing rather than by taking cover. Health and armor are non-regenerative on all difficulty levels except for the easiest and instead are replenished with the health and armor packs which are littered throughout the game. Available health is represented by a percentage number on the screen. The combat is high-paced and frenetic: The levels typically consist of a series of elaborate arenas, in which the player will defeat a set number of re-spawning enemies before proceeding to the next. Enemies consist of soldiers with rocket launchers, charging bulls, gigantic robots that fire lasers and rockets, and shrieking suicide bombers without heads. The player can carry a number of weapons, including shotguns, a minigun, a rocket launcher, a quad laser gun, and a cannon. Ammunition is scattered across levels that the player must pick up, but players are also suggested to explore the level's environments to find secret items including more health, ammo, and weapons that are obtainable regularly in later levels. Unfortunately, some items are trapped and may trigger a spawn of more enemies.
