2 star Hotels=best return on investment. See the math? Can't build on sabotaged space, build a base of 2 star (if not hotels then the next best investment) then sabotage until there's nowhere for computer to build. No contest. Choices are obvious.

It will freeze too.

Was a fun game, I was not able to get passed using the 2nd house.... A bit hard...

Maybe you should indicate how much square you need for a building. As whatever building you clic on : you only see that it needs "one square" to be built on, which is false.
Also I found the CPU really non-aggressive and sometimes it's hard to move around the map as the mouse isn't take into account.
Nice idea though!
