Hello there. I'm one of the developer/founder of Tribal Hero.
If it makes you feel any better, we are committed to never having pay features which will skew the gameplay. When we eventually add some premium features they will be more for convenience rather than to make you perform better in the game. This should help keep the game as fair as possible.
We have a lot of plans to improve the map. We're only a 2 person team doing this as a hobby and have to REALLY prioritize our work. Some of the things I want to do for example:
- Add terrain (rivers, mountains, etc..) and have the terrain affect the gameplay. E.g. travelling through rivers may take longer and different types of sailing research could improve the travel speed on water.
- Allow players to further customize their cities (statues, fountains, etc..)
