The one thing people advocating a F2P business model is that they really don't know that a F2P game isn't really free. For example, if HiTech would go the F2P route, you can be sure that they will only give you the base planes for free (planes like the Spitfire Mk IX, P-51D, FW190D-9, etc.) while charging you if you want to fly the top tier planes like the La7, Spitfire Mk XVI and the monetization probably wouldn't stop there. Want to carry 1,000 pound bombs on your Mustang? Sure, pony up some money to buy or rent (for a tour) for the ability to lug 1,000 bombs. Want a new map? Sure, pony up some more money. Want to drive tanks? Pony up some more money to buy or rent them. You would probably end up paying more in a F2P game then you would for a subscription based game.
There is a reason why the majority of F2P games released fail within the first year.
