Islanders is a game of pure simplicity and relaxation, if you have any stress in your life give this game a go and either listen to the soothing game music or throw on your own relaxing music and just pass the time for an hour.

Pros:

Simple gameplay.
Long term replayability.
Relaxing

Cons:

Islands can be a bit too small.
Not a lot of variety in buildings.(not a con for everyone, i like a lot of meat in my games)

Additional critiques:

No mod support will lead to this game eventually dying out when either people get bored of its simplistic nature or when the developers stop supporting it, i am a big advocate of modding and a feature such as this brings so much life to a game to the point a games life span can go from 4 years to 20+.

More variety in locals could be interesting currently we have a ruin type island, a snowy island, a grassy/plains style island and a desert island, if i were to make some suggestions i'd like to see a jungle island and maybe more 2 island maps with 2 different locals.

This game also has tremendous possibility for future updates, DLC or even a sequel, in recommendations for a DLC or sequel (i'm a big sci-fi fan) a trip into space and instead of colonizing islands you're colonizing asteroids.

Final Notes:

Islanders is a great game that anyone should pickup, and as a brief message to the developers, you have a game of great potential in your hands and i will continue to keep my eyes open for future content from you guys and i hope you continue to make amazing games such as this masterpiece you've made.
