Is Space Empires IV Worth Buying?

[Taipan]

I have been bitten too many times by Game Reviewers that say "This game is great, 95/100..etc" only to find the game is crap once you buy it.

I've downloaded the demo & I'm hooked, and I like to know if it is worth parting with my hard earned money to buy the full Version.

As the game is worth about $100 Aussie dollars, can anyone give me an honest accessment of the game.

Is it re-playable; does it have a preticablity after a while; does the AI give you a challenging game; etc, etc

Thanks
