Finish Splinter Cell: Blacklist

Sam Fisher in the dark with three green lights; the stealth game at its most systemic.

Sam Fisher in 2002, with light and shadow as the whole mechanic.

Sam Fisher in Indonesia and Paris, and the asymmetric spies-versus-mercenaries multiplayer nothing has matched since.

Fisher undercover inside a terrorist cell, with a trust meter that makes every mission two missions.

Mark and execute, interrogations in real rooms, and objectives projected onto the walls.

Ezio Auditore in Renaissance Florence and Venice; the game that made the series.

Ezio in Rome, an assassin guild and the first multiplayer; the tightest Assassin's Creed.

Hack San Francisco with DedSec; the sequel that found the fun.
