Overall, Munin falls into a middle of the road game for me. While the artwork, music and story were strong, the actual gameplay fluctuated between too easy and way too hard far too frequently, and the controls were unreliable enough to add to the difficulty. If you're good at spatial recognition and are interested in a cheap (it's currently on sale on Steam) puzzler that you will spend a fair bit of time on and is nice to look at, pick it up. If you're not (like me) and you're looking for something a little easier, look elsewhere.
Overall, Tropico 5 makes a solid entry into a genre already populated by great games. It has some drawbacks, but it gives you a good construction game while offering enough variety of play to offer many hours of fun games and great replay value.
