The game has been criticized because many feel it gets dull and tedious. However, they have said that a better combat system and a farming system will be implemented soon. Also when the prelude ends I believe you will be able to attack/destroy other tribes and there will be more politics and warfare involved.
I think the reason it feels like all you do is make a tribe and then your done is because of the lack of animals and creatures (content) in the game.
This is the type of game that will never end. If it can succeed in having a decent sized dedicated player base. But it just needs more features and tools to get to that point.
I guess I have bigger goals. Ive not even built 1 building, nor have I even raised or level 1 time the ground. ( I have made some roads).
Ive been having a blast the last week (not counting the crashing).
You all know Im not a "fanboi", so me saying that should mean something.
Lots to do in game, just you have to figure out what YOU want to do.
