It would be great to hear a review of these from a user.
If you're happy with cfs3 then I can't recommend the MAW, PTO and ETO addons highly enough. MAW especially is a masterpiece of freeware modelling and creation. The PTO work is also excellent but needs other missions etc adding as it was only ever intended to provide a foundation - the whole and feel of it is very good. The ETO brings together all the best cfs3 mods plus plenty of new ones in one hefty package if you've got a decent pc and can turn the sliders up the eye candy factor is very high
There's a write up about it lower down on these forums. Oh I forgot to mention there's also a Korean addon too!
At present the MAW, Korean Skies and PTO sites are all down as the host has been ill. They should be back up and running soon, I'll let you know.
