ClassiCube

-MINIMUM-

OS: Windows 98 and above, Mac OS X (Mono or Wine), Linux (Mono or Wine), Raspberry Pi 3 or above (Mono or Wine)

CPU: Older Pentium models can work, along with low power netbook processors, and ARM chipsets.

RAM: 512 MB, but you'll want more (2 GB) if you're running a 64 bit OS.

Storage Space: 100-200 MB minimum avaliable space. When game files, caches, and crash and/or chat logs add up, it can be over 100 MB in size.

GPU: It will work on low end GPUs, including integrated graphics.

TL;DR To sum it up, any computer manufactured in the early 2000s could but it'll be so slow it won't be playable. Get something newer.

-RECOMMENDED-

OS: Windows Vista and above is recommended for a better experience.

CPU: 2.00 GHZ clockspeed or above, two cores or more recommended.

RAM: 4 GB should be enough for smooth gameplay.

Storage Space: 1 GB dedicated to ClassicalSharp and it's associated files.

TL;DR Any computer manufactured in 2010 or later should be great for ClassicalSharp.

Do tell me if I got something inaccurate.
