1. 常见：这是指游戏实体版本非常容易找到和购买，市场上有大量供应，并且价格相对较低。
2. 有卖：游戏实体版本仍然比较容易找到，但可能在市场上的供应量有所减少，价格略有上涨。

这些等级可以帮助确定游戏实体版本的相对稀缺性和市场价值。
再加一些特殊分级：
绝迹：这个级别代表了实体游戏拷贝的绝无仅有的稀缺性，以至于是否真实存在都成了一个谜。最多只能在一些流传的影音资料或历史文献中找到证据来证明它可能存在过。这是游戏界中的极其稀有和神秘之物。
特供版：这种游戏拷贝与正常发行的标准版不同，包括对设定、剧情、人物，以及可能对未成年人造成心理创伤的内容（如暴力和血腥）的删改。因此，特供版的存世量相对稀少。
专供版：这类游戏软件不是常规发售，而是发行商提供给特定人群或组织的特殊游戏软件。由于这类拷贝一般不允许二次销售，存世量也相对稀有。
自制软件：自制软件是由个人或组织在未获得硬件平台开发商的授权下自主研发并发行的游戏软件。这些自制软件通常需要对硬件平台进行修改以便运行，且它们的存世量可能因制作质量、知名度等因素而不同，因此它们的存世量既包括稀有的，也包括非常普遍的版本。这种类型的游戏通常比官方授权的游戏更加多样，因为它们的制作和分发存在法律和技术限制。
盗版：盗版指的是未经原始游戏开发商的合法授权，非法制作并分发的游戏拷贝。这些拷贝可以包括原版的二次修改，如粗糙的本土化或其他改动。盗版通常是非法的，可能存在版权问题，通常被视为非法或未授权的复制品。这些拷贝在市场上可能存在品质问题和法律风险。
原型版：原型版指的是开发商内部泄漏的未完成版本，这类游戏相比于正式版缺少了很多内容。它们一般没有固定形式的拷贝，通常数量稀有。这些版本通常是游戏开发的早期阶段，对收藏家和游戏历史爱好者来说，它们代表了游戏开发的珍贵历史遗产。

8. Special Edition: These game copies differ from the standard releases, often including alterations to settings, plotlines, characters, and even the removal or alteration of potentially distressing content for minors, such as violence and gore. Consequently, the supply of special editions is relatively scarce.
9. Exclusive Edition: These game software copies are not part of regular retail sales but are provided by the publisher to specific groups or organizations. As these copies are generally not authorized for resale, they tend to be rare.
10. Homebrew: Homebrew software is developed independently by individuals or organizations without the official authorization of the hardware platform's developer. These games often lack a standardized physical copy and may require modifications to the hardware platform to run. Their rarity varies based on factors like production quality and popularity.
11. Pirate Copy: Pirate copies refer to game copies produced and distributed illegally without the authorization of the original game developer. This can include alterations to the original version, such as rough localization or other modifications. Pirate copies are typically illegal and may pose copyright issues, often seen as unauthorized reproductions with potential quality issues and legal risks.
12. Prototype: Prototype versions are game copies leaked from a game developer's internal development phase, lacking significant content compared to the official release. These prototypes usually don't have a standardized physical copy and, as a result, are relatively rare.
