Line #6 YMMV/CallOfDuty1


1	* EvenBetterSequel: ''United Offensive'' is seen as a massive improvement over the already impressive original game, thanks to the addition of new weapons, vehicles, and multiplayer maps. It's telling that ''[[VideoGame/CallOfDutyWorldAtWar World at War]]'' five years later tried to innovate on the ''[[VideoGame/CallOfDuty4ModernWarfare CoD4]]'' multiplayer by bringing back mechanics from ''UO''.
2	* FanNickname: Quite a few people who discovered the original, United Offensive and Call of Duty 2 [[SequelDisplacement after playing the next-gen games]] are now calling them "Call of Duty Classic". The first game was released with this title as a downloadable game after ''Modern Warfare 2''[='=]s release.
3	* FranchiseOriginalSin: ''VideoGame/CallOfDutyVanguard'' caught flak for its highly anachronistic take on the war, but ''Call of Duty'' fudging historical accuracy for gameplay or story purposes dates all the way back to the first game of the series: perhaps most notably are the endings to the American and British campaigns depicting, respectively, a wholly-fictional mission to rescue prisoners from a Dulag Luft camp and a two-man infiltration of the battleship ''Tirpitz'' that never happened. The difference with the earlier games is that they at least had a dedication to historical authenticity - for instance, given the insane amount of time and resources the British put into trying to sink the ''Tirpitz'', it's easily ''believable'' that they would have sent a pair of SAS commandos to plant bombs ahead of one of their many air raids - and the errors they made tended to be extremely minor, e.g. the [=StG=] 44 showing up in its production form in 1942, instead of modeling a slightly different prototype variation that existed at the time and was superficially near-identical. Even ''VideoGame/CallOfDutyWWII'', which could be considered the start of the real problem (made by the same dev team as ''Vanguard''), was half-and-half with this: the dev team admitted that player choice took precedence over historical accuracy for multiplayer, but that the campaign would be as authentic as possible, with its most notable errors only being on par with those made in other games e.g. several Russian guns showing up in German hands ([[TheEnemyWeaponsAreBetter an extremely common occurrence in reality]], "wrong" only because the game doesn't include the theater where they had common access to Russian guns). ''Vanguard''[='=]s problem was simply taking a step beyond that by choosing to focus its singleplayer around a special forces group [[PoliticallyCorrectHistory with far more women, people of color and Axis defectors in it]] than would realistically be allowed in the 1940s to handle the kinds of operations ''[=CoD=]'' usually depicts special forces undertaking, to say nothing of how much wackier the multiplayer got - to give a good idea, despite the multiplayer ostensibly also being set during the war, it includes a map taking place on the set of the first ''Film/{{Godzilla\|1954}}'' (released 1954), allows you to play as Music/SnoopDogg (born 1971), and as of its final seasonal update includes the F2000 assault rifle (entered production 2001).
4	* HilariousInHindsight: The protagonist of the Russian campaign in ''United Offensive'' is [[VideoGame/CallOfDutyModernWarfare3 Yuri]] [[VideoGame/CallOfDutyWorldAtWar Petrenko]].
5	* NintendoHard: ''United Offensive'''s campaign was considered to be very difficult during its release. The actual gameplay was identical to the first game, as expected from an expansion pack, but the new weapons gave the Germans an edge they didn't have - the Germans (and the Russians) got a semi-auto rifle to match the Americans having ''two'' in the first game, and suffice it to say, it wasn't tested quite well enough in the hands of enemies. Fights that wouldn't cause one to break much of a sweat with the original game only giving them MP 40s and [=Kar98s=] become nail-biting tests of endurance (and patience, and hammering the quicksave key) as enemies that were only a problem in extreme close range suddenly paste you in two shots from a hundred yards.
6	* OlderThanTheyThink: ''United Offensive'' was the first game in the series with a SprintMeter, though it was [[DamnYouMuscleMemory bound to a different key]] (Alt by default) and covered a much shorter distance before running out; it was not until ''Call of Duty 4'' that it became ubiquitous in the series.
7	* SequelDisplacement: A vast majority of the fanbase have never played the original game, ''United Offensive'' or even ''Call of Duty 2'' - the current ''[=CoD=]'' fanbase largely consists of console gamers while the first game was (and ''United Offensive'' still is) exclusive to PC, and the series didn't become the household name it is now until ''Call of Duty 4''.
8	* ThatOneLevel:
9	** ''Pavlov's House'' is a nightmare even on Normal difficulty, specially during the last segment of the mission where you have to defend the house from a German counterattack with respawning German soldiers trying to ZergRush you constantly while having to destroy tanks with stationary anti-tank weaponry.
10	** The second half of the Foy mission in ''United Offensive'' comes to mind. As if sniping tankbusters while EVERYONE IS SHOOTING AT YOU isn't enough, the final part of the mission is just as brutal.
