I'm 61 now and I've been buying and flying flightsims ever since 1991 ... at the time I found that non-radar sims were quite awful really. All you'd do is fly around aimlessly looking for a moving pixel in the sky. So basically, even though going through an uncountable number radar flight sims, I always avoided the others, especially propeller plane sims or WWII sims.
However in 2007, I must have had some money to burn, cause I bought a discount edition of 1946 for 10 euros on impulse and have been hooked ever since. Il-2 is nothing at all like the early non-radar sims.
