Is a bit hard at the beggining, but once you've learn is the best WWII flight simulator!!!
The Good: Large quantity of WWII planes to choose from, realistic flight, you can put a custom difficulty turn off or on the things you like or you dont, great sound makes it feel real, realistic take-off and landing, realistic crashes.
The Bad: too many controls (if all are used), takes time to learn to kill enemies.
Really you have to buy this game, even though at the beggining is a bit hard when you learn evrything is a great game one of the best flight sim. of all.
