Command and Conquer Tiberian Twilight/YMMV


 * Darkness-Induced Audience Apathy: The game forces you to choose to work for Colonel James, an extremist who deceives you into helping her get revenge on Kane and fighting your fellow GDI soldiers, and Kane, who is working to save the planet but for his own selfish reasons. With no sympathetic sides to the conflict, there is hardly anyone worth rooting for. The crappy ending is just the icing on the cake.
 * Esoteric Happy Ending: The Tiberium Control Network has ended the Tiberium threat for good. Kane is no longer of this world, and humanity has lived to see another day. However, the GDI Commander is dead, Kane is still out there, the deaths of countless millions is now called into question with his ascension, and the many, many questions players have about whatever just happened are quickly swept under the rug with almost no fanfare.
 * Goddamned Bats: Spanners, dear God! They are small, flying repair craft that cost few points. Even though they are completely unarmed, they become absolutely horrendous when in large numbers, since they can nearly instantly repair any damage you deal to them or any enemies around them unless you have a large number of units that beat them on the Tactical Rock-Paper-Scissors. The Nod Scalpel also counts.
 * Harsher in Hindsight: As seen below, after Kane has ascended through the portal a random civilian scoffs at the notion that Kane is truly gone. After the game's extremely poor reception and the series put on indefinite hiatus, it seems unlikely we'll be seeing the Nod mastermind again after all.
 * Never Live It Down: The many, many liberties taken with the game's mainstay features, such as the omission of base building has been met with this by many. The game's ending however only added further salt to the wound, and is widely accused of having possibly killed the franchise entirely.
 * Sequelitis: The game suffered this bigtime for its dramatic departure from the traditional Command and Conquer experience, having removed many of the series' trademark gameplay elements for no discernible reason. Its infamous ending, intended to be the conclusion of the overall series ultimately failed to answer many of the central questions that drove the main story, and as such is widely considered a tone-deaf entry that undermined the once-popular RTS series.
 * They Changed It, Now It Sucks!: Originally meant to be a Gaiden Game, Command and Conquer 4'' features no base building, no resource gathering, no sidebar, no Scrin, and a population cap, so it's kinda understandable why long-time fans are upset.
 * Imagine your response if an iconic RPG series like Final Fantasy had one final game, and the last game was a first person shooter. Betrayal does not begin to cover it.
 * Older Than They Think: Though the console ports of Red Alert 3, Tiberium Wars and Kane's Wrath all had population caps long before Command and Conquer 4 did.
 * Took the Bad Film Seriously: You really feel sorry for Joseph Kucan who played the eponymous Kane for one last time in what's supposed the Grand Finale for the Tiberium Saga given the poor critical and fan reception of the game.
