I personally own Dynasty Warriors 2, 4 Empires, 4 Xtreme Legends, 5, 6, and 7 and have played 3 at a friend's house
I dislike 6 the most, mainly because it was a sudden change in gameplay. 7 brought back the original gameplay, but introduced a few new upgrade systems. Story / Musou mode has changed so the story is specific to each kingdom, but your character has been set in stone so that reduces the flexibility.
Conquest mode is fun at first, but it becomes extremely tedious and potentially boring if you want to get 100% completion of the game.
All characters can use any weapons, so the attack patterns are all the same. The only difference is the musou attack and a special attack when the character uses their "set" weapon.
The graphics are great, but there's a huge potential for improvement. Overall, it's a good game if you're a fan of the series.
I gave in and just bought the game anyway. My inner dynasty warriors fan convinced me lol. That said its very much like the last dynasty warriors game I played which is 5. Only this time there a shit lot more weapons and every character has just become a "skin" for me to use. Its still a pretty decent game though
Nope I wanted it but just haven't got it, XL is the expansion of the original it has a feature that you can share with the original, it also has few new characters and play individual character story's, and some other stuff I can't remember, here's the link to the info [link]
