Hey that's right! I forgot I had Empire Delux Masters Edition, it was 2.50 at a library sale I gotta dig that one up. That's a good game, takes a little while to get through a game and the graphics are a little oldish, but yes that is the sort that I'm lookig for. I may well get the updated version of it.
As for the sale I tried and liked the demos of Remote Assault and TWE, and they are now sitting on my desk

. Horse I tried, but I already have Interstellar trader to satisfy my economy gaming needs.
I'll try out the people's tactics and the others mentioned, thanks for the recomendations.
