You really should give play by email a chance. It can be great fun. Games usually take a few months, with turns generally once a week, sometimes every two weeks. While you could invest more, it certainly doesn't need to take up more than an hour or so a week of your time. In fact... I may have to see if I can find a game now. It's been a few years!

I dunno I'm kind of hesitant to do that because I'm much better face to face and appealing to emotion than I am writing out convincing speeches to get people to support me but you and the above commentor convinced me so I'll have a look around when I get my holidays soon

Do you know where I could go to find people who are playing it through email?

I used to play at DipWorld, but it looks like it's a lot less active lately. It appears that the most active community now is at the Diplomatic Pouch. The site design leaves something to be desired, but after some clicking around, this appears to be a decent place for a new player to start: http://www.diplom.org/Email/

It's been years but http://www.redscape.com/ is one location to play by email.

Personally I play a bit on my phone using the Droiddippy app. However you can also play via web at http://droidippy.oort.se/web.

I've played face to face and by email. They are really different games but playing by email is really quite fun. The tempo is different and the games take on an epic quality. A typical play by email game will lasts 3-6 months and can go longer. You'll often be waiting days to find out the results of some critical moves. Over email there is an entirely new class of interpersonal tactics ("Oh I must have missed your email asking for support - I'm so sorry!", forwarding messages from other players, etc.)
