I would like to say that I am a major CMBB / CMBO fan and play all of my games by PBEM due to the timing of when my opponent and I are able to play (he does his turns at 4:30am before work, and I do mine at night when I get home from work). We usually keep 4-5 games going in PBEM at any given time. I don't share ANY of the thoughts from the poster earlier on this thread who is disillusioned with this game or the company.
But I would strongly favor any kind of a "trusted" PBEM option, such as they apparently use in TacOps. I think that this would be a great feature because it would enable us to finish our PBEM games in a shorter time period, which would let us play more games!
It doesn't have to involve re-write of the engine or to be secure - I am confident that my opponent isn't going to re-run a scenario to get better results. If you don't know your opponent that well, use the "old" way for scenarios.
PLEASE PLEASE PLEASE put some kind of trusted PBEM option in the next patch 1.02!!!
