Hi Gabe, welcome to Forum and thanks for your question and interest!
Please consider the following first.
If you're completely new to Amiga world, and you would only like to play some Amiga games and nothing else, well, while that is certainly possible with AmiKit, there are probably more simple solutions (check Amiga Forever
on Windows, for instance).
That is because AmiKit aims to provide a full AmigaOS experience and beyond. That involves enhanced operating system capabilities and features. And while we made everything as easy as possible (everything is pre-installed and pre-designed), some basic Amiga knowledge is required to fully enjoy (and appreciate) the AmiKit package.
Now, that being said, and to answer your question regarding hardware - I don't know AtariVCS specs so I don't really know. AmiKit is available for Windows, Mac, Linux and Raspberry Pi. The first three use WinUAE emulator running on Intel machines, the Raspberry Pi edition uses Amiberry emulator running on Raspberry's ARM CPU, obviously, and a customized 64-bit Manjaro XFCE system.
If your machine is able to run Ubuntu, then go and try the free «AmiKit X for Linux» on it: https://www.amikit.amiga.sk/x
The newer AmiKit XE for Linux is very similar, if not slightly easier, in terms of installation and setup, so if you're good with the X version, you will like the XE version too.
Hope it helps?
