RenPy Games are almost visual novels and also easy to run. Just extract and run game .exe on PC. Just extract and run game .sh on Linux. Just extract and run game .app on Mac only if you find it in the game directory.

Run English Games
Most English Games are very easy to run. Just extract and install then run for installable version. Just extract and run for portable version.
Run Japanese Games
Most Japanese Games should be running with Japanese Locale. So there are two options for you to choose.
1. On Win7, just click Start -> Control Panel -> Clock, Language and Region -> Region and Language -> Administrative Tab -> Change System Locale and Select Japanese. Restart and all errors and crashes are gone.

Play Eroges on Linux, Mac and Mobile
Sorry, most eroges have only PC version. But Flash Games, RenPy Games and HTML5 Games are cross-platform games, so if the game is made with Flash, RenPy or HTML5, you may run it on Linux, Mac and even Mobile. Many Patreon Games are made with these game engines. You can try them on Linux, Mac or Mobile, but it's not recommended, because PC is obviously the best platform to play the best eroge.
