此文章为整理steam上多区域版本可共存的游戏，即包含不同区域、特供、不同平台（Mac、Linux平台）可同时入库的游戏整理，其实还可以衍生出原版与重置版共存（例如生化奇兵的原版与重置），原版与特别版或者加强版共存（例如蝙蝠侠的原版和年度版），原版与测试版共存（例如幽灵行动:荒野的原版与测试版）等等，但此贴只放出区域限定与平台限定，所以Remastered、Special Edition、GOTY、Enhanced、Multiplayer、VR、Demo、Beta、Test、movie、software等不包含在内。
如以下不包含在内：
由于现在的礼物政策与区域key激活政策比以前严格太多，而且还有多数游戏已经绝版，现在再想收集已经很难，需要自跨钱包区域（有的游戏有多个区域特供版本，想要激活得自跨多个国家，不推荐）、收集全球礼物等等才能入库，还是量力而行吧。
另外其中很多游戏会出现媒体测评版和开发者版，一般来说这种都是弄不到的，所以就都剔除了，排名不分先后，会有遗漏，欢迎补充。
