videogames are mostly standalone and viable, as are OS (less-and-less), and apparently steve gibson makes a pretty nice living off of spinrite which is a hard drive maintenance and recovery tool. Which I suspect gives insight on the viability of the standalone software space. Needing extreme performance and inately interfacing with the computer&#x27;s hardware. As a maxim, if you can put it on the web without sacrificing anything significant, you probably should.
