This is just about perfect as a management SIM, unless you like something complex. It's quick - an entire season can be played in about five to ten minutes. You can hire and fire managers and players as well as build the stadium. There's an Arab billionaire upgrade you can buy for a relatively small some of £2.99, and it gives you £50m to build your club. In the early stages, this could last a few seasons, though I suspect in the top league it might not go so far. There are cheaper options, or you could try it with no upgrades at all, depending on what kind of challenge you want.
At any rate, it's a simple and addictive game you will surely enjoy.
Absolutely brilliant little game, simplicity personified but wonderfully addictive. Kind of like a weird, much quicker paced football manager, apart from you don't get to pick your team, but making the signings, controlling the facilities and sacking a manager doing badly is great fun.
