The first installment in this series is clearly shadowed by the second.
Well, it's a decent game but nothing more. It was refreshing change from Dune II (simply because no other adequate RTS was released during that time) and the music/sound effects are OK.
The game is slow - either badly programmed or simply meant to be slow. The enemy is stupid and the entire experience is lacking.
The Bottom Line
You should probably play this just to get an idea how much better the second game is.
