I am not a big fan of RTS games but I found this one appealing for its solid mechanics, theme and replayability (due to the good AI and random map generation geature)
This game is awsome. Its a shame that it never really took off. Its like age of empires but with boosted graphics and some sweet units and buildings. I'll admit even i didn't like it so much at first but after playing it with two of my friends I quickly became hooked on my favorite god Hades and his demonic army that i was allowed to create. Take age of empires 2 and some WarCraft elements and you get one of the most entertaining RTS's i've played.
