Rome was fun, but Medieval II was so much more enjoyable from a game play point of view. More units, more tactics and the ability to "discover" the new world before 1492!! Shogun 2 was a disappointment, all the units were lack luster and it turned into arrows ftw tactics. Really wanted to like Rome 2, but damn, everything that made Rome total war great was missing from Rome 2.
I thought Rome was the most polished, but I got into Medieval 2 more because I could relate to England and France more readily than to "Seleucids" and "Carthaginians". Plus gunpowder only takes like 100 turns (200 days, I think) to kick in, and I like things that go BOOM.
In Rome 1, you could ruin the enemies' siege just by sallying forth and not doing anything. The battle would start and the enemy wouldn't have any of the siege equipment they've built. It made it so you could always get reinforcements there in time.
I honestly can't remember, the only thing I remember about MTW2 sieges was sending in a spy who can open the castle gate and using cannon bombardment for making short work of structural defenses (walls), which also killed all the guys on the wall, obviously. It was just OP.
The motivation of this poll topic is to get me playing this series again, instead of Warband all the time. This series has what Warband doesn't, and vice versa.
