Gamevil's ''Pro Baseball'' series, also known as the ''Baseball Superstars'' series in the United States, is a mobile baseball game series. The first game came out in 2002, and the series have had 30 million downloads in total (first in Korean history).

The selling point of these games is the "My League" mode (beginning from Pro Baseball 2006) which allows the player to raise a baseball player and induct him to the Hall Of Fame.

Also, from Pro Baseball 2010 and onwards, a story line has been added where the protagonist of My League mode could meet "heroines" (who appear as special playable characters in the game) and develop a relationship with them.

The series chronology goes as follows:

* ''Pro Baseball 2002'' (2002)
* ''Pro Baseball 2004'' (2003)
* ''Pro Baseball 2005'' (2004)
* ''Pro Baseball 2006'' (2005)
* ''Pro Baseball 2007'' (2006)
* ''Pro Baseball 2008'' (2007) (released as ''Baseball Superstars 2009'' in the US)
* ''Pro Baseball 2009'' (2008) (released as ''Baseball Superstars 2010'' in the US)
* ''Pro Baseball 2010'' (2009) (released as ''Baseball Superstars 2011'' in the US)
* ''Pro Baseball 2011'' (2010) (released as ''Baseball Superstars II'' in the US)
* ''Pro Baseball 2012'' (2011) (released as ''Baseball Superstars 2012'' in the US)

----
!!This game series displays examples of:
* AccidentalAthlete: Medica and Psycher started out as this in ''2008''. Same for Luna the maid in ''2012''
* AlternateContinuity: While ''2010''[='s=] Roze arc ends with [[spoiler:the little heiress going back to her own country,]] in ''2011'', we learn that it was the protagonist that had gone "far away", leading the players to think that he died; [[spoiler:that is, until the happy ending of ''2011'''s Roze arc, where we learn that he actually went to the Majors.]]
* CaptainErsatz: Except for the Gamevils and the Swallows, the other eight teams and the players of the teams are based on the eight professional baseball teams of Korea ([[NoExportForYou at least,]] [[LostInTranslation that's how it is in the Korean version...]]).
* ContinuityNod / MythologyGag: Several of them:
** In ''2010'', [[HelloNurse Medica]] says to the protagonist that she "has been close to [[TheRival Psycher]] for three years". Both Medica and Psycher debuted as special characters in ''2008'', and appear in ''2008'', ''2009'', and ''2010''.
** In ''2011'', a certain exchange between the protagonist, the baseball team's characters, and Medica, is directly copied from ''2010'''s exchange (the protagonist even lampshades it).
* DemotedToExtra / ChuckCunninghamSyndrome: Leony, one of the "heroines" of ''2010'', has only been mentioned once by her papa Leon in ''2011'', and Valentine, another one of the "heroines", is simply not mentioned at all.
* ExcusePlot: ''2009'' did have a rival plot, but the rivals appeared few and far between.
* {{Expy}}: YMMV on this, but 2013 girl Haley seems to have the combined personality of Erin Andrews, Deadspin, and a stalker, rolled in one.
* {{Fanservice}}: ''All'' of the female special characters. The coach in 2012 and 2013 is this as well.
** And the cover models (known as PB girls). Just look at [[http://channel.pandora.tv/channel/video.ptv?ref=na&redirect=prg&ch_userid=hidemeto&prgid=33361352&categid= this]] and [[http://image.gamevil.com/mobile/game/2010_baseball/images/400-265_cf.swf this]].
* GameplayAndStorySegregation: During the eighth year of My League mode, the protagonist lampshades this, citing that his romantic overtures, ''in no way'', should have taken place over eight years. Interestingly enough, the 2013 version has amended this, with the girlfriend subplots taking about three years to complete.
* HelloInsertNameHere: The protagonist in "My League" mode.
* HospitalHottie: Medica.
* JerkWithAHeartOfGold: Senior until ''2012''. Then he and the Captain switch roles and bodies. Also ''2012'' PB girl Bora, although it's because [[spoiler: she's still emotionally distraught over the loss of her parents, and only acts this way to the protagonist because]] he apparently says stupid things.
* NoExportForYou: New installments, beginning from ''2008'', only get released in the US a year later.
* OlderThanTheyLook: Psychey.
* PutOnABus: Psycher in ''2011'', where we learn from his little sister Psychey that he enlisted in the military after he "broke up" with Medica in ''2010''.
* RobotBuddy: Pitching Machine MK-3 debuted in ''2008'' as something similar to [[StarWars R2D2]], appeared as a "friend" for Roze in ''2010'' in the form of a pitching tank, and then appears again in ''2011'' as a humanoid robot (again in the service of Roze).
* SequelDifficultySpike: What most of the fanbase see ''2011'' as, since most of the AI problems that made the games incredibly easy were fixed. The AI itself also drastically improved as well.
* ShesAllGrownUp: Roze's artwork has changed from "little girl" to "young lady" in ''2011''. [[BaseBreaker Not all of the fanbase has liked the change, though...]]
* WhatHappenedToTheMouse: Kao Joe, who has appeared from ''2008'' to ''2010'', and even had some screentime in ''2010'', is gone without a trace in ''2011''. Roze has also mysteriously vanished from the series, with her last appearance being in the Americanized BS II.
