Actually, I think that almost the only thing we miss right now is the nice GUI, almost anything else is moddable in Rome, just like NWN is (okay, it has more options, but it's an RPG, so it needs a lot of scripting to even be able to produce good modules). I think R;TW community is definately going into the same direction as the NWN community, it might take another TW title, but I'll think we get there.

And I do think that is the future, with the newly pay-for-extra-official-content system they recently implemented (will be operational soon, check the nwn site) being the next type in the gaming business. You could make anything you want, but official content will probably be better, and with a reasonable price, keep the money for the develper flowing to make extremely nice patches.

Bioware is definately my favorite developer at the moment, they seem to genuinely listen and interact to their community, and produce fabulous results.
CA is getting there, and I hope they can manage to become equally good. At least they have the right spirit so far:
a lot of moddability, interaction with the community, even though the official forums are kind of .. well.. bad. EZ board as official forums don't look very professional IMO.
Both communities feature at least a user group which is capable of understanding the value of a good community and want to work on it. Some communities are less 'mature' (both literally and abstractly).
