Nothing to compare with. Its like comparing Civ III to Doom III. The only common thing is that they are both strategy games. M2TW is 40% a strategy game and 60% a tactical game. At this 40% EU2 is a better game. As a whole the two games are uncomparable. They even dont have the same era. EU II is a renessance (SP) and Napoleonic game (1400-1850) and M2TW is a ... medieval game (1080-1550).

I had been equaly addicted with EU2 and MTW, if this is something relavent.
