I’m going to call them Lane Pushing Games (LPGs). It’s the best moniker I’ve seen and it’s a great blog by a game designer/developer I know who goes by the name of Softmints. If you have any interest in DotA and the myriad maps that came about in Warcraft 3’s day (and Aeon of Strife which started it all) I’d highly recommend you read it. http://lanepushinggames.wordpress.com
I’m calling this part one because I probably won’t say everything I want to say in one post. Let’s find out.
