I was aware of so many good reviews, 8.9@IGN, 9.0@Gamespot but somehow I found resistence to the game because I like more TBS 4x games than RTS. To my complete surprise (well only partial due to so many good reviews and the fact I love homeworld games) I really enjoy this game, and I'm currently playing it. And by the way, Entrenchment and Diplomacy are great expansions.
I'm not biased by anybody, I really was surprised to discover such an amazing game. I criticise Gamespot's review that says "well the game takes so much time ..., you loose sleep etc etc as a negative point" .. don't understand that. If you like to play only couple of hours you play a small map, you want more play the medium or big maps.
