This is a really old question and a really old solution.

It turns out that piracy is actually a service problem. Services like Steam and GOG provide a decent enough service that piracy becomes less common.

Many games on GOG are at the tail end of their sales cycle (i.e. were released on Steam long ago) trying to eke out a few more sales, are from small indies for whom any attention at all is good attention, or are very old^H^H^Hclassic games that garner purchases for nostalgia's sake by older gamers that can afford more discretionary spending.

1) Modern games are enormous and as long as services like GOG let me re-download my library it frees up literally terabytes of space on my disk array for pirated movies and other things that benefit far more from piracy than games do.

2) I don’t want viruses. I don’t want viruses more than I want to avoid paying $1-$20 for a game (as if I’m anywhere near caught up enough on my backlog of games from the last 40ish years for buying games at full launch-week price to ever make sense, lol, I do that like… once every several years, all the rest are very cheap)
