Fast Outlaw: Asphalt Surfers itself looks a little like a car racing sim, but don't be too fooled - it's in the lane-hopping genre, i.e. you tap (or swipe) to move lanes, left and right, avoiding lorries going in each direction, avoiding blocks dropped from planes (no, really) and trying to scoop up blocks representing in-game cash.
This is all set against a background of fast animated, on-rushing scenery - the impression is of super high (beyond normal reaction times) speed, though it turns out that this is normal. It's normal because the developers want you to crash and require repairs, at which point you'll soon be paying real money to get the virtual money.
In fact, there are many, many ways to spend both in-game cash and real money, including avoiding in-game waits, buying new cars, customising your existing ones (right down to the number plates!) and buying power-ups.
Being honest, the sheer amount of finance-derived activity left a bit of a bad taste in my mouth - if the core game had been more innovative than just nudging left and right every now and then 'on rails' then I'd have persevered longer and the in-app-purchases could have been justified in terms of hours of gameplay.
Sadly, despite the sumptuous animations and rendering, the core game is a little 'GameBoy'-ish and 'Fast Outlaw: Asphalt Surfers' didn't grab me at all. Your mileage may vary, of course - comments welcome!
PS. With screenshot after screenshot of freemium interaction, you'll get the idea - you'll spend as much time juggling virtual and real money as you do dodging lorries - haven't most players got enough to do, finance-wise, in the real world? For the umpteenth time, developers, just give us a great game for a modest fee and some utterly optional extra IAPs for the really keen. Hint: see Riptide GP2.
