This probably has been posted before but the title speaks for itself. Why do you think tc_hydro wasn't very popular. In my opinion it was the fact that Territorial Control was basically Attack/Defend but both teams have to attack and defend. Also, that Territorial Control is/wasn't a mode worth investing time into to justify making new maps for it. In my eyes Territorial Control wasn't a good idea but tc_hydro was a good idea on paper as far as theme and aesthetics but its execution was poor. At least Powerhouse is ok.
