Obvisouly inspired by the old impressions/sierra games, Lethis PoP is a worthy game of the genra.

For old veterans mastering the walkers system and space optimization, it will feel rather easier than the old-school city managing games like pharaoh or caesar III, especially since the dev made the choice not to include a military aspect into the game.
For newcomers wanting to try for the first time such type of games, Lethis PoP will be perfect. You'll learn everything there is to know in the first few missions of the tutorial and then can improve yourself over the course of 20+ missions in the campaign.

The art is gorgeous, the music is calm and not too intrusive, the animations are well-made and the maps for the campaign and sandbox mode are different enough to challenge your skills, especially in the latest parts of the campaign.

With a longevity of around 40hours for the campaign, 100% achievement will require a minimum of 50hours. Nothing impossible and i have enjoyed every minute of those.

This game was made by only 2 developers and i think is worth its price. Waiting on Lethis PoP II now :D
