I noticed that the People Can Fly is listed as a developer for Gears of War while in fact they only did port (which is listed below, properly). I suspect it's the problem with the Template:SMW Developer games (it's read-only, so a mod is required to edit it), even though I don't know exactly what needs to be changed for the template to work properly. Can someone look at the issue? Thanks in advance :)

Not exactly. If I remember correctly, PC version has additional chapter (most likely developed by PCF), so I think PCF should be developer with a note that they ported it as well.
Soeb would probably know how to handle these kind of situations better, try asking on the IRC channel.
