Dune II: The Building of a Dynasty

The Good
Well, it was one of the first RTS around. It's got decent music. Actually the very best computer beeper sounds I've heard and the MIDI sound on real sound cards is not bad either.

The Bad
It's got horrible graphics. They are horrible by today's standards and they were horrible back then when the game got released. Heavy tanks looked mostly like deformed pigs. The computer AI is just about as intelligent as a brick - to counter this it cheats massively (for example, it can place it's buildings everywhere - even over your units). The units themselves are ridiculous. If a rocket tank that generally shoots in a 90 degree arc in front of it is the highest technology available, I'll start to cry. Game tactics/strategies is nonexistent. Might require a little more thinking than original command&conquer due to the fact that the missile turrets are so powerful. The amount of units and buildings is strictly limited (25 units/side,99 buildings/map), and especially on the last two levels you are pounding both limits frequently. You cannot control more than one unit at a time, making a coordinated attack impossible.

The Bottom Line
If you REALLY want to play every single RTS out there, then go for it. Otherwise, almost any RTS is better than this.
