During the last Punic War and annexion of Greek policies Siracuse city was completely destroyed and now should be rebuilt to become central Roman trade outpost in Southern Italy.
Some unorganized groups of greeks are still active in the region, but there will be no big troubles with them. 2-3 legions shall be enough. More serious problem is complex landscape and logistics as well as trade relations due to high customs and unavailable land trade. Plan your city wisely and perform effective trade policy.
*I provided two files in ZIP archive so you may choose both to test and play.
1st - the .map file with the standard resources.
2nd - .sav file with one distinction - olives are available and vines are not (which better corresponds to real Siracuse climate conditions).
