This is probably the worst Kairosoft title I've played, and I've played almost all of them.
First of all there is pretty much nothing to do 90% of the time. I'm already on my 10th or so cruise and only have like less than 10 shops/facilities to build. Besides powering up existing facilities with items, what else are you supposed to do while cruising, exactly? Every few minutes you buy an investment, that's it?
Second of all whenever I buy an expansion, my setup of facilities is completely ruined. Whose bright idea was it to add a level to the MIDDLE of the ship? Say I had 2 floors, and I add one. Everything I had on floor 2 now gets forcefully moved to floor 3 with its arrangement ruined, due to floor 3 having a different floorplan than floor 2. Now I have to pretty much destroy everything on floor 3 and rebuild it from scratch, with floor 2 completely empty now. Wtf?
Thirdly there's pretty much no instructions on the gameplay at all. Randomly your investments will suddenly have "no effect", without any known reason. For example I invested in the tourism of a country with less than 100% tourism, and in the end it said "no effect", so my money was wasted.
This is pretty much a dumbed down version of mega mall story with at least 50% less things to do.
