Well, it's just a matter of opinion, he's simply disagreeing with you
Honestly, if it was up to me i would do a bit of both. I would like having a 3rd party industry around CoD to give it exposure, but i'd limit that to single player content.
What i wouldn't support is a situation where 3rd party payware becomes a standard for online gameplay.
You might have a 1000 dollars in add-ons, but the majority won't and if it becomes necessary to have as much as half that before going online, then the online aspect will gradually wither and die. The reason FSX flourishes is that add-ons are completely optional and up to the player
So, i would mix a bit of what both you and Tomcat are saying so that the biggest amount of people have the most amount of options available to them. Otherwise we just end up ostracizing one part of the community in favor of another and things go downhill.
P.S. As for the clouds, the
default FSX clouds are 3D. The REX clouds are 2D photos
