I love RTW. Sure there are some bugs in it, but there were some bugs in MTW as well.

I just can't go back to the gameboard feel of MTW. I have played it a few times since I got RTW, and the amount of interaction in RTW just blows MTW out of the water.

You actually march your armies around the map in RTW, you can actually get ambushed. The Diplomacy, though irritating at times, is head and shoulders above MTW diplomacy.

The graphics are amazing compared to MTW as well. When I go back and play a game of MTW, the difference in the quality of the graphics is glaring. (and I used to think the graphics in MTW were amazing.)

RTW is much better at providing a realistic world for you to become immersed in without the super micro-management of a game like 1503 AD.

It is great.
