Yep yep. MW, as is, is a wonderfully simple system and my group, coming from D&D 1st edition/2nd edition Seems to have had a good time with it. I personally prefer a little flavor in my characters and campaign so have incorporated some spot rules from MW and other systems as well as some of my own house rules stuff but this is for my own satisfaction.
This is the beauty of BRP and MW. It's so simple to take the system and make it your own by adding and subtracting what YOU want. That being said... er...typed, the more material I add from other systems or even create for use in my MW games, the more I realise I may be over complicating an already great system.
I've had a few veterans on these boards nonchalantly point this out to me, in a very nice way, and I failed to listen to their insightful wisdom time and time again. But they're correct. MW is about having fun with rules light roleplaying. Take what makes sense to you and your players, and don't over complicate it more than you have to. The fun is on the board, not in flipping through the books.
