LOL " real playing" makes me laugh.
Okay s no, you don't have the instant reaction and easy comradery of a Face to face or even VOIP game. But, (and I caveat this by saying, it depnds on the GM and game) PBP can be very close to the same thing just spread out over longer periods of time between responses.
I have 1 game I run PBP currently and I play in one as well.
The game forum we use is RPOL.net and it has a Die rolled, and private messaging in posts so that it can run very similar to a regular game. The Game I run currently uses the "Hack Master" (new edition) system, And I run it, even combat, The same as I would in face to face.
I plan to run my RM/SM game the same way.
I used to be down on PB games, as I had a few bad experiences years ago, But again, With the right GM, Right group, it is a Decent play. and IMO is better than not playing at all.
