《最终幻想X》以計算時間战斗(Count Time Battle)[4](美版称“条件回合制战斗”,Conditional Turn-Based Battle缩写CTB)系统取代自《最终幻想IV》起使用的即时战斗(Active Time Battle、ATB)系统。ATB的理念使用了实时元素,而CTB为等待玩家操作的回合制形式,因此CTB设计可让玩家在无时间压力的环境下选择指令。屏幕右上方的圖表时间轴列出了之後數回合中的行动对象,而所選行动会可能改變回合顺序。玩家在战斗中至多能同時控制三名角色,並可透過换人系统随时替换参战队员。可以打出高伤害的特殊攻击极限技以“过载”名义在《最终幻想X》中重新出现。大多数技能要用按键输入来强化威力[5]。虽然角色最开始只能在受到强力攻击后增加过载,但之后可以切换为其它解锁过载增长方式[6]。
游戏有三首歌曲使用声乐元素,其中有日本流行乐民谣《真好》(素敵だね)。歌曲由野岛一成作词,植松伸夫作曲,日本民谣歌手Rikki演唱——音乐团队在寻找冲绳歌曲歌手时与Rikki签约[72]。日版和英文版游戏都使用了《完美》。和《最终幻想VIII》的《Eyes on Me》与《最终幻想IX》的《Melodies of Life》类似,游戏片尾曲使用了弦乐版的《真好》。其他填词歌曲是:比尔·缪尔以英文演唱的重金属片头曲《Otherworld》;以及由日文假名演唱,在游戏中多次出现的《祈子之歌》[73]。
日版《最终幻想X》还内含收录采访录像、画像制作的附加碟片“The Other Side of Final Fantasy”,《蓝天之翼》、《王国之心》和《最终幻想:灵魂深处》的预告片,以及《最终幻想XI》的首个演示视频[86]。游戏国际版于2002年1月在日本为《最终幻想X国际版》名义,2002年5月发行的PAL版亦继承了国际版的要素。国际版在原NTSC版上增加了一些特性,如和“黑暗”召唤兽及飞空艇上超级头目“Penance”的战斗[8]。日本国际版还收录了《永远的安宁节》——连接《最终幻想X》及后传《最终幻想X-2》故事的14分钟的影片剪辑[87]。影片剪辑以《永远的安宁节 最终幻想X-2 前奏》名义收录于《无限:沙加收藏版》的附加DVD中。它于2003年10月31日在欧洲首发,使用英文配音[88]。
国际版和PAL版都收录了附加DVD《Beyond Final Fantasy》,内含对游戏开发者及两名英文版配音员——詹姆斯·阿诺德·泰勒(提达)、赫蒂·布里斯(尤娜)——的访谈。此外还有《最终幻想X》和《王国之心》的预告片,游戏概念图和促销画廊,以及Rikki演唱歌曲《真好》的音乐视频[89]。2005年,收录《最终幻想》和《最终幻想X-2》的合辑《最终幻想X/X-2 Ultimate Box》在日本发行[90]。2012年12月18日,收录游戏的《Final Fantasy 25th Anniversary Ultimate Box》发行[91]。
史克威尔还出品了许多商品与书籍[92],如《The Art of Final Fantasy X》和三本《Ultimania》攻略,一系列画集与攻略本,书籍皆由DigiCube在日本发行。这些书籍或收录《最终幻想X》的原画与游戏攻略,或深入补充游戏设定;之中还收录数篇游戏设计师采访。[93]。
日本和西方媒体都给游戏打出高分。日本电子游戏杂志《Fami通》和《Fami通 PS2》给游戏打出接近满分的39/40[123];而在《Fami通》2006年上半年的史上最佳游戏读者票选中,游戏获得首位[124]。另一日本游戏杂志《The Play Station》给游戏打出29/30。三本杂志特别称赞了游戏的情节、画面和影片[123]。游戏在GameRankings和Metacritic的汇总得分为91%和92/100[111][112]。制作人桥本真司称总体评价“极好”,得到媒体的称赞和奖项[59]。

Should these souls remain in Spira, they become fiends that prey on the living. Sad, isn't it? The sending takes them to the Farplane, where they may rest in peace.
