This is an easy recommendation. I think anybody with even an elementary interest in building and management games could get several hours of enjoyment out of this, although at time of writing I'm sitting at about 27 myself. Well worth the price of entry.

That's the TL;DR, but allow me to expand on why.

Project Highrise is essentially a game about confronting your own lack of foresight. When you want to put in that new block of apartments, you're going to have to deal with all the choices you made on lower floors, and if the lobby is 30 storeys down, it's going to be tough to fix problems unless you're willing to think outside the box.

Sometimes the progression can feel a bit odd, though. As other have pointed out some of the requirements to get certain businesses can seem a bit esoteric (we need more sports bars before we can build that accountant's office!), and with how the prestige system works you can unlock a lot of the high-end apartments by focusing exclusively on offices (and vice versa), but these aren't huge problems for me.

A few other reviews have pointed out the limited replayability. It is true that there do seem to be a few optimal setups; not in the sense that there is exactly one way to play the game, so much as sets of systems that work well together when you get them running. I don't know if that's too much of a problem. For one thing, the devs have been pushing out the odd gameplay change to help keep things interesting, and a few of the scenarios make for a fun challenge. For another thing, no game is ever infinitely replayable, and for what it cost me? I've already got my money's worth.
