Here comes the party pooper.
Please don't delete or edit this post, let people express less-than-good opinions, too.
Yes the game got much better with each patch, and yes you can tell that there is a great deal of work behind it.
However, I think that publishing a paid expansion now wouldn't be a good idea.
Even with my medium-high end PC (i7/970, 12GB RAM, GTX680) the frame rates often drops close to unplayable, especially on take off.
Antialiasing hasn't been taken care of, yet. That means, planes are very hard to tell apart until you're very close to them.
Also, I still have a problem with the Hurricane, where low-res textures are superimposed to the hi-res ones (as shown in the patch thread and in a bug report)
I could keep going but I think I made my point: right now CloD is a great game but it still needs some fixing before an expansion can be published.
Personally, I wouldn't buy an expansion right now, unless early customers get a special deal. On the other hand I would buy the sequel if some time after the release, positive reports start popping up and everyone is happy with it... but for some reason, I don't think that's going to happen.
Now don't get me wrong, I still believe that CloD is going to be the greatest flight sim game ever. All im saying is that I won't invest more money in it, until im sure that im not going to get ripped off again.
Everyone can get ripped off once, but getting ripped of twice, by the same guy, and in the same way... well, that's not going to happen.
So, make the game match the promises and I'll be happy to keep buying expansions.
