Steam is one of the biggest, they have most of the latest releases and older games to at reduced prices, and guess what specials and freebies. h t t p s : / / s t o r e . s t e a m p o w e r e d . c o m / j o i n / GOG is mainly for older games and there are a lot of free ones to be had, just do a goggle for the games you your looking at and your OS or Operating System, IE Windows 10 / 8 / 7, Unix Ubuntu Etc, like this. "Games name, how to play on OS." This should tell you if you can play it, and if you need to do something first. w w w . g o g . c o m There are a lot of MUD's about, or Multi user Dudgeons, also space games like Star trek on line & The Elder Scrolls on line, if your into a type of game then just do a goggle with say Space games or Card games Etc, but before you down load do a goggle for a Review of that game, some have spy wear in them, the review should warn you.
