I hope you won't mind if I promote my site, http://backstabbr.com. We felt like none of the other Diplomacy sites on the Internet had a modern interface (and they weren't compatible with mobile phones) so we set out to fix that. We also have a Sandbox that you can use to play around with potential moves. If you give it a shot, I'd be eager to hear your feedback. Thanks!
I'm going to need to actually see how the controls work during play, but signup and creation are far better than any of the other web judges I've played under. Good job!
The Sandbox is definitely where I'd recommend you start. It'll give you an immediate feel for how everything other than press works. (And the press is pretty straightforward.)
Well, our website is only partially responsive (if that's what you mean) but you can definitely use the site from any of the major phone platforms. To the best of my knowledge, none of the other online Diplomacy sites are fully playable via phone.
And yes, the game is fully implemented. We lack a lot of the alternate rules and maps you can find on other sites, but our goal was to make the best possible experience for the core game instead of trying to cater to all the variations.
I'm afraid so. We presently use Google exclusively for user management. For whatever it's worth, the only thing we take from your profile is your email address.
When you look at the resolve phase, to have the lines/units tween into their new position (or bump one another in case of a draw), makes it easier to see what went where and makes it a bit juicier.
Ah, yes. Well, I can tell you that one of the things we've talked about a fair amount recently is changing the color of displacement/retreat move orders, so that they are more visually distinguished from a regular failed move.
