Anvar, me too. Have a stock campaign going now with a few patches/mods geared toward fixing things vs. graphic only additions. While I like the various megamods, I also like setting the game up with what I think is "realistic", whatever that means, vs. only using someone else's interpretation.
No complaints so far.
