And what is your impression personally for the Beta, will the finished product be a grail for an RTS fan as myself?
Beta 2 was as fun as most released games, not to mention far, far more stable.
We're now on Beta 4, and one month from release, and there is
plenty of fun to be had.
I have also read that some think that the gameplay is too slow, boring and always plays the same. Is this true or does this just represent someone who has just played the smallest levels or somehting similar?
Well, singleplayer
does get a little repetitive -- Beta 4 doesn't really have an AI worth mentioning, as they didn't have time to get the AI out the door,
and the Vasari,
and all the other fixes they've made. So, since this was a multiplayer beta anyways... no AI

As far as playing slow, its only slow if you play it on slow. You can play on normal / fast speed to -- normal most people like fast, well, only speed freaks care for that these days
