Dear All It has been announced that Civ5 will be the most moddable Civ game ever. However, a number of unrealistic restrictions seems to apply to the gameplay and it is not clear whether or not they could be modded. There has been a number of highly realistic and enjoyable mods in the past. IMHO, the Vikings mod for Civ2 and the Revolution mod for Civ4 are both especially outstanding examples of excellence. People who feel that historical realism is an important part of the Civ game are hereby invited to join the new Realistic Approach Institute social group. Modders are especially welcome. The purpose of the group is to discuss the ways to make gameplay more realistic and possibilities to model historical events in Civ. I have been playing Civ games from the 1st version. I am a professional computer programmer and study history at university. I have tweaked past Civs for my own purposes but have not made any full-featured mods this far. However, if Civ5 really offers as good tools as promised, this will change. All suggestions are welcome.
