Good idea but isn't it a few years too late?
I applaud the effort but why now?
I suspect that the playing of CMBB and CMAK will go one for many years. If all the support for these games were placed into Battlefront, then if Battlefront were to shut down all this material would then be lost.
I think of PanzerBlitz, which is still being played, and what would have happened if all the new materials for that had been entrusted to Avalon Hill. However I don't think the fully developed and mature fan supported sites are going to fold up - why would they? So what exactly would this new site provide?
Now here is a problem, I have about 200 CMBB and CMAK scenarios - how would these be transferred to this new mega site? Electronically? ok. Slowly uploaded as I did from the old TSD to TSDII? I don't think so.
Again I think the idea has merit but the present environmnet may not support its success.
