Initial impressions are very positive, as your lovingly detailed rally car sets off around a lushly appointed track against a full field of five competitors. You'll gawp and nod in wonderment, thinking for a second that mobile gaming truly has taken a large technical step towards its console brethren. Then you'll reach the first corner and most of these illusions will be smashed like the front-ends of so many of this year's Wales Rally contenders.
The lurching, lumbering pace of it all will strike you first, with progress slowing considerably when things get busy onscreen. Then you'll notice the stuttering reaction when your car makes contact with a competitor, and your heart will drop a little more.
