In the system requirements section, "minimum system requirements" could be "barebone specs," "base system needs," "essential hardware requirements." Operating system is specified as Windows versions, so no change there. Processor: "Intel Core 2 Duo 2.0 GHz or AMD equivalent" - maybe "AMD dual-core" as an alternative? Wait, "equivalent" can be "matching," "comparable," "similar." RAM: "4 GB" is a number, but maybe "4 gigabytes," "four gigabytes," but that's not three alternatives. The user might not want the actual numbers changed. Wait, the instruction says "no changes to proper nouns," but numbers and technical specs are part of the content. So maybe those should stay as is.
"Highly" could be "Very|Extremely|Greatly". "Compressed" might be "Zipped|Minified|Shrunk". "Download" as "Obtain|Acquire|Grab". "Gaming Experience" could be "Gameplay Adventure|Interactive Entertainment|Digital Simulation". "Budget" maybe "Low Cost|Affordable|Economical". Euro Truck Simulator 2 Highly Compressed Download
Wait, the original example uses "x" as "x", so each word in the spintax is a single alternative. So for each word, find up to three alternatives. So for example, "extract" becomes uncompress. The user might not want the actual numbers changed
This could be tricky. For example, replacing "The" with That might not always work, but perhaps the user just wants three alternatives regardless of grammar. Maybe some words might be out of context, but follow the instruction strictly. "Highly" could be "Very|Extremely|Greatly"
