Absolutely brilliant games, plenty of levels and expansions available online to keep them going. Still being played pvp 10 years later... They should do another one. I loved these games so much I bought freespace and red faction just because of the connection.
I agree with the negatives that the game got stuck in a rut at times, but I enjoyed the world and storytelling (and personality) a lot that i didnt mind trying a fight many times or turning in circles at times. There's not enough steampunk in games to pass this one :)
