I've been asked as a favour to download some free/legit games and bring up to some colleagues as they have a virtually unusable internet connection. Must have a reasonable single player mode. Multiplayer not likely to be used. Must be a standalone installer - trying to mess around with steam is not going to end well. I've been out of the gaming circles for a long time now so need some recommendations. Game and download link would be great. Legit links only though please - too easy to pickup malware from generic upload sites.
