So, for my own records and the benefit of members here is a list of F2P games that I enjoy. These games do NOT include games that are completely free such as Minetest, Battle for Wesnoth, Open Arena - Just because I know Asad is going to say something lol . If anyone has any suggestions to add to the list let me now. I generally like games that have a good business model that dont screw you over in other to make money.
