Do any of you fellows remember FS2000? That was absolutely riddled with bugs and defects just like CFS3. Now look at Fs2002 and FS2004. Two outstanding games that work well.
CFS3 was a huge leap in graphics and things. Fly low over land on CFS2 then do the same with CFS3 with the Autogen on. I think thats an amazing difference.
Sooner or later M$ needed to change the graphics engine used by CFS. CFS2 is just about the best that can be got out of that engine so to move forwards a change was needed. And CFS3 was that change. Of course there were bugs and glitches, there are in all software. Especially new software. CFS4 will have the performance of CFS3 with better graphics, better hardware compatability and fewer glitches. Remember the change needed to be made at somepoint. And M$ thought that CFS3 was the time to do it.
I personally like CFS3. The planes look good and sound good. Whats more I can fly around my part of the world and recognise features in the landscape. (If you hadn't noticed, CFS3 offers the most accurate terrain mesh I've seen in FS and CFS.)
I know Tempest misses the turning fights of CFS1 and 2 but I personally found these fights too easy. Especially when you could single handedly tackle a flight of 8 Oscars in a Hurricane.

I find a duel with an Go229 in a Tempest MkV in CFS3 most rewarding. Especially when you finally get a good hit and you see his engives catch fire.
And as for future sims, I want an North Africa/Mediteranian CFS. Just think about launching an attack on Taranto with a dozen Stingbags. Sadly though this is unlikely to happen because the Yanks didn't really play a part in that theatre. And I don't think Americans are too willing to buy games that don't really involve their country in any way at all.
