Real blitzes can be great but you might have to arrange them where you are. Get friends hooked on Dominions. Then you can get games that process every 5 minutes for a whole day worth of gaming.
On here the closest you can get to that is to pre-arrange to host a game and declare that the players need to commit ahead of time to being available something like 5am to 9pm on Saturday (be sure to say WHOSE 5am you are referring to, what location on earth or time zone you mean). Setting the game to host every XX minutes even if the turns arent all in can be fun also.
If you use SoloPlay for only testing purposes then you might want to look at the mini-map battle simulator example. There are many threads about it. Here is one link...
