When I say half-assed, it's because the base game is basically a Tropico 3 remix. Little was done to improve the design. It was like an EA Madden game where they just updated the graphics and made it bigger. This left a lot of their core customers disgruntled around the time of release as problems in 3 re-occurred in 4. Having not played 3, I only know this from having tried to resolve problems and finding that the problem persisted from the predecessor and that the problem was not solvable on my end.
I don't know if all of these have been resolved, but, for example, they had decorative rock overhangs on some of the maps that prevented road construction beneath them. The "fix" they put in for those was the removal of the overhang. This had originally caused those maps to lose access to whatever portion of the island was past the overhang. They also have some areas where the area between obstacles is so thin that you cannot place a road through, again, denying you access to a % of the map and resources. This latter issue was never addressed while I actively played.
They made maps quite a bit bigger in 4 as opposed to 3 (so I'm told), but limited the amount of road you can lay to an amount insufficient to create complexity across the larger island. So the distant locales of your island only had main street if you even bothered. Many SSes of cities showed half the island going unused because of road limitation.
There is also a hard pop limit, for which there is esentially nothing you can do, which limits how much you can use your island. That limit is like 1500 or 2000, and as you're expanding into the region of that limit you'll see some really hardcore job switching. If people switch off from the teamsters (trade depots) your income will plummet as your imports and exports stop being trafficked.
This is just off the top of my head. I haven't played since the Modern Times DLC was released. They've released like 3 more that probably addressed some negatives. I know I had some design and balance gripes, but I can't recall the specifics. I think they sell it really cheap though. At
$10 for every single thing(ends March 15th), it's a really good value.
I adore the humor in it. The advisors in Tropico are fantastic. Everything is voiced and colored with exaggerated communist/capitalist overtones.
TL;DR My concerns may be dated.
