World of Warcraft
"World of Warcraft" was first announced by Blizzard at the ECTS trade show in September 2001. Released in 2004, development of the game took roughly 4–5 years, including extensive testing. The 3D graphics in "World of Warcraft" use elements of the proprietary graphics engine originally used in "Warcraft III". The game was designed to be an open environment where players are allowed to do what they please. Quests are optional and were designed to help guide players, allow character development, and to spread characters across different zones to try to avoid what developers called "player collision". The game interface allows players to customize appearance and controls, and to install add-ons and other modifications.
Warframe
Warframe is a free-to-play cooperative third-person shooter video game developed and published by Digital Extremes. Originally released for Microsoft Windows in March 2013, it was later ported to the PlayStation 4, Xbox One, and Nintendo Switch. In "Warframe", players control members of the Tenno, a race of ancient warriors who have awoken from centuries of cryosleep to find themselves at war in a planetary system with different factions. The Tenno use their powered Warframes along with powerful weapons and abilities to complete missions. While many of the game's missions use procedurally-generated levels, newer updates have included large open world areas similar to other massively multiplayer online games. The game includes elements of shooting and melee games, parkour, and role-playing to allow players to advance their Tenno character with improved gear.
