Hmm - it turns out that I have less time to play games these days, so I found time by writing about some of my favourites.
My current favourite game (I go through fads) is Simutrans - an Open Source Transport Simulator, that happens to run nicely on Linux, Mac, Windows and even the iPhone.
First I compared it with OpenTTD, a transport game I had been playing before
OpenTTD vs Simutrans - The Linux Transport Simulation Showdown
.
As I played it more, I decided to share my best tips (which I am still collecting) with other players on
Simutrans Help and Tips
.
I may be on a roll with games articles for a short while, but will be back building robots or power things soon enough...
