That was odd. My plan for the afternoon was to download and play Marvel Brothel. Instead I put on the new Alan Partridge, entered a kind of autopilot and ended up downloading and playing historial turn-based strategy game Bronze, of which you can get the demo here.
Despite being the kind of game Alan Partridge might enjoy, Bronze is pretty interesting. The base concept is a kind of enhanced Go- you need to capture as much of the board as possible, and you do this by putting down different developments. Army camps capture all tiles around them except farms, forts protect tiles, ziggurats capture farms, towns capture all neutral tiles around them, etc. I kind of enjoyed myself, plus missions are interspersed with vague history lessons. Curious? Give it a shot.
