Should I buy this game?

The movement system in Dom is sufficiently different from SEIV that I don't think you'll have the same problem. There is also alot of information contained on the main screen once you learn what the filters do. F1 is a great screen to help you manage your provinces and even commanders, though there is still some room for improvement.

All in all I'd say go for it, its not really that similar to SMAC, but it has its own charm.
