I posted this 3 weeks ago in another really old thread.
If anyone is still interested in a fantastic single player RPG game series that offers very little eye candy but tons of content to keep you busy for hours on end, you will not find a better deal than right now on Geneforge.
I have played and beaten 3 of these games, still working on the 4th and will likely replay some of them to try different characters/builds.
Right now, Steam is offering %70 off these games and you can get the entire bundle of 5 full games for just 5.99. The Steam Sale is over, but its still just 19.95 for all 5 games.
Go to Steam Store and type in "Geneforge".
