Like, I would assume, most people who bought this game, I picked this up as kind of a joke purchase. I thought it'd be something I maybe fired up for ten minutes and then dropped; something I could mention off-hand to the guys at work who think it's hilarious that I have played more than 50 hours of Euro Truck Simulator. However, it was surprisingly engaging - my first 40 minute session felt like a third of that and I only stopped as I was interrupted, and to my surprise I've since returned to the game.
It's a fairly straightforward management game, but so far seems well-balanced, introducing mechanics over time and neither too challenging to feel like good results are attainable, nor so easy that you feel like you're just coasting.
The basic mechanic is building up your building to build up your business (a la Unholy Heights), combined with a very rough sort of worker management - you can hire and fire staff, assign rooms full of them to accounts, educate them and essentially add modifiers to their mood/productivity etc. by hiring other staff. There are a variety of roles covered, so balancing the ratios is the part of the game you'll have to think about the most.
Full disclosure, you will spend a fair bit of time just waiting - I presume that will be reduced as the game progresses and you start earning more money, but I've reached a slightly uneventful plateau where I just have to wait a couple of days to add a new building, and that's a little tiresome even on the highest speed.
I like the art style - it's nothing novel, but it's well executed, and you should be able to see at a glance whether the visuals are for you.
The music is a little cheesy, but I guess that's to be expected from a game about a call centre.
Overall, I'd recommend this as a cheap purchase (I got it in a bundle), but this price seems pretty fair anyway. Don't buy it expecting an immersive cinematic experience, but for the money, it's pretty good.
