Where is the best place to download completely free, single player RPG's?

Go re-read the ToS you agreed to. In it youll find that TH doesnt condone piracy of any kind, especially members assisting other members in where to find pirated software. You should know better than this.

The Ubuntu software center has some great open source RPGs. Also just google open source RPGs for whatever platform you are running

For example, Windows...http://osswin.sourceforge.net/games.html

Edit that link above is pretty old: here are some more current ones for Linux...http://opensource.com/life/12/10/5-new-rpg-games-linux

and as usual wikipidea does most of the work for you: http://en.wikipedia.org/wiki/List_of_open-source_video_games

P.S. not a fan of illegal downloads either, you want free opensource is the way to go and if you like make sure to contribute

http://store.steampowered.com/ for free to play rpg.

Goto Games in one the tabs ,where u will see the RPG games >click and u will see all the RPG games available for free or paid.

Very simple. Move the mouse to Games and you will see a drop down menu. Free to play is the first choice.

I will point out that none of these are completely free game where there is no money involved. The type of "pay walls" varies by game. Some are pretty loose and some are pretty stringent and others can be crippling.

Pinball Arcade is listed as Free to Pay. I have on my Nexus. You get one free pinball game (referred to as tables) which is Arabian Knights. Pinball Arcade has many different tables, but you can only score so high before game play ends and it informs you that if you want to unlock the table you need to pay money. Every month one of the tables is completely free to play. You can play the game 24/7 if you wanted to, but only for one month for that particular table. I actually like Pinball Arcade and I am considering purchasing a set of tables (called Seasons) for $30 per season; specifically Season One since it has the best collection of tables.

I have only just started playing MMOs; specifically Star Trek Online (STO) because it is mostly a single player game (the campaign / story) but with MMO elements like PVP or PVE zones. The game is designed by Cryptic and based on many review it seems to have the most lax pay system of all MMOs (Star Wars The Old Republic appears to be one of the more restrictive). Many people have stated they were able to play the game absolutely for free and completed the three different story lines several times over.

I've have been playing for about a week and I would have to agree that there does not seem to be too many restrictions for free players. One "pay wall" is the 10 million Energy Credit (currency) limit imposed on Free to Play. Sound like a high cap, but the better ship / equipment can cost on the 10's of millions to a few hundred million credits. However, such things are not required to complete the storyline. But naturally elite ships / equipment can make space combat easier.

I realize that I have been going on for while about STO, but the point is really about how "wallet friendly" Cryptic games could be. If STO is not your type of game, then check out Cryptic's other game Neverwinter is based in the Dungeons and Dragons world. I have not played Neverwinter, but it might might be worth looking into.
