还真是，当初玩儿1.6就是这界面

这个仿远古版本的steam皮肤我看到过，名字叫OG-Steam，是在github发的，地址

仿2004年steam客户端的皮肤，看上去确实挺有意思的。
github页面上的说明：
An Internet Time Warp
Steam, in its current form, is hardly recognisable when compared to early releases. However, you may be surprised to learn that, despite innumerable changes made to Steam in its 17-year lifespan, its Graphical User Interface system, VGUI (which is built into the Source engine), has remained virtually unchanged. This has allowed me to create a skin which very accurately replicates the look and feel of the Steam client from around 2004. I have future-proofed this skin to the best of my ability by including as few files as possible (and, therefore, fewer points of failure). Ostensibly, Valve has plans to re-write the Steam client in JavaScript; we have already seen several moves in this direction. Until such time, welcome to 2004.
This version has been tested on Windows running the latest version of the Steam client (As at 2021-05-21).
直接丢进机翻输出的结果：
与早期版本相比，目前的 Steam 很难被认出。然而，您可能会惊讶地发现，尽管 Steam 在其 17 年的生命周期中发生了无数变化，但其图形用户界面系统 VGUI（内置于 Source 引擎中）几乎保持不变。这使我能够创建一个非常准确地复制 2004 年左右 Steam 客户端外观和感觉的皮肤。我已经尽我所能通过包含尽可能少的文件（因此，更少的文件）来证明这个皮肤的未来故障点）。表面上，Valve 计划用 JavaScript 重写 Steam 客户端；我们已经看到这方面的一些举措。在此之前，欢迎来到 2004。
此版本已在运行最新版本 Steam 客户端的 Windows 上进行测试（截至 2021-05-21）。

不过要注意的是，听说这个皮肤的库和好友列表是外挂的（可能，也许，大概），所以安全性可能不太能确定。如果有哪位老哥懂的话，可以帮忙看一看。
如果这层楼没被吞，看得到的话，拜托回复一下。

我有上古版本的，只不过连不上服务器了，根本看不了里面有啥

额，上古版本的库好像不是这样吧，以前我记得好像只有左边坟字迷宫能点出游戏吧
