I tried to get back into MTW after RTW - and I acknowledge it's a better game, but RTW graphics have just spoiled me. When I first saw a battle in RTW - and I got RTW rather late (about a year after it came out) - my jaw dropped to the floor and didn't come back up for two weeks. I admit to having been a sucker for graphics.
Medieval, though, sucked me in with pure gameplay goodness back in the day.
