Now I'm not the smartest guy when it comes to IT and such, so I have no idea how this would be implemented or how it would work, but I often find myself playing Diplomacy games and forming alliances with several other nations. However, I find it difficult to tell everyone important information and discuss issues between all members of the alliance. That's why I propose an option to create a group chat during a game, which functions exactly like the private chat, but involves whoever you want.
For example, suppose I'm Norway, and I'm in the "Scandinavian Alliance" with Finland, Sweden and Denmark. If I need to alert the other members of my alliance about a threat (let's say, an aggressive Russia) and ask how we should handle this problem, I would need to privately message each individual nation, then receive their responses individually. For the purposes of this scenario, let's assume that each have their own solution and reasons for the solution.
- Finland wants to sign a peace treaty, as they have too many vulnerable territories on the border
- Sweden wants war, because "the only way to fight fire is with fire"
- Denmark doesn't care, because Scandinavia isn't being attacked and he doesn't care about Turkey
Either I can take all of these suggestions and reasons and decide by myself, which is going to go against the desires of two thirds of the alliance, or I can relay each option, scenario and reason to each member, which is not only time-consuming but will still limit the amount of discussion put into something that could have a very profound effect on Scandinavia.
This is only one example off the top of my head, so it's not exactly very good but I hope you get the idea I'm trying to get across. In-depth discussion and distribution of information would be much easier with a group chat (preferably one where you can add and remove members easily) and would have a much more positive effect on gameplay.
PS. I know there's probably far more important things that Fizzer hasn't done yet, but there's no harm in posting.
