I’m so skeptical of the “making it work offline is too hard” argument, I’ve personally RE’d dozens of these titles with no source access, often with anti tamper, and succeeded. Very few titles are genuinely unpreservable to some extent. For example, the VAST majority of Unreal Engine games are trivially preservable unless the developers have taken steps to strip server code, and even when devs do take those steps “reading between the ifdefs” isn’t the worst thing in the world.
