/vr/ - Retro Games

Halo has pioneered the following in videogames:
-Dual wielding
-Recharging personal shields (every FPS today copies it)
-Dedicated grenade button
-Dedicated melee button (melee is actually useful in Halo)
-Complex characters (master chief, arbiter)
-Involving and deep storyline
-Limited weapon inventory for added realism
-Saved the Xbox
-Made LAN parties cool
-Saving and sharing replays
-First ever console FPS to include a map editor
-Perfectly streamlined online play
-Vehicles
-It is so good that games nowadays are referred to as "Halo clones," and some, like Killzone, try to be a "Halo killer"
-Orchestral music (before it everything was just bleepbloop synthesized music)
-AI that becomes more intelligent on higher difficulties instead of just having more health.
-The concept of instant-kill melee attacks from behind (Team Fortress 2 copied this)
-The infamous crouch-jump exploit, which can also be extended to the double jump
-Realistic sniping mechanics
