Primordia is a good game, every puzzle is logical and sometimes there are several possibilities to solve them. Actually there are several endings to the game either. But I only gave it a 3 because it is too short. You start in the desert and then spend some times in the city. That's it. The story is not that interesting too. You guess what is happening in the middle of the game and the end doesn't tell you anything more. Actually you have to make your own end as the bad guy's motives turned out to be logical and you can question why you spent so much effort to defeat him. So I would say it is a good game but I couldn't really identify myself to the hero hence the average rating.
