It would be good to indicate if you are open to engineers in Europe or the UK and what hourly salary they should be expecting. The other locations you list are considerably cheaper and might indicate you aren't paying enough to support talent from these geographies.
Really liked the idea and spent 15-20 mins playing it. Would be good to save your progress. To be more realistic I shouldn't be able to buy a house after about 5 months of salary. Make the house prices 10 times more expensive if you want it to more like real life!
Also It's not clear to me if I take the job I can't go to university? I took the job in the absence of another choice, like real life if I got a great alternative offer I would leave the job and do that instead.

Why not? If you have the cash for the downpayment, a fixed contract, and the property is within 4-5x your yearly salary, you can definitely get a mortgage. I've seen people do that within a month of arriving in a new country & job, depending on the local market it's a very smart thing to do.
