After playing this game for nearly 3 years now,these are my game suggestions.
1 is to have 2 bookmakers
2 extra islands
3 star coins in the loot of doing fairy tale adventures,to the level 50 players that is.
4 have some kind of ship battles that will give out loot,new buildings to make ships to protect your island.
5 generals to move faster,they do in pvp adventures.
6 when an adventure is done some kind of screen will show to see what troops were lost in total.
7 introduce a grape farm building to make wine to sacrifice to the gods in return to get new battle buffs
like lightening bolt or strike that can be used in adventures.They have done this in earlier settlers pc game.
hope this helps
