Can't judge it until we see it. And I don't think it'll be a problem if it is less complicated than Civ III or Civ IV. After all, isn't Civ a broad church? There's nothing wrong with having a hard core version like Civ IV for the serious player, and a lighter version for those new to the game. After all, we don't disrespect someone now just because they like an older version or because they never play at deity.
I for one am going to welcome all the CivRev players as comrades when the game arrives.
