The graphics are great, controls and all that are great, the touch screen stuff is okay too (except the chase game, that's terrible).
I've played every Dynasty Warriors game out there, except the portable versions.
I wasn't going to play this game, as I usually don't play portable ports. But seeing it get surprisingly good reviews convinced me to try it and I'm glad I did.
I'm glad they went back to the old weapon system. They also brought back items and orbs. The story is told well, but isn't presented as good as previous titles (specifically DW5) they put in conquest mode, which is a great addition, they also put in Create a Warrior and that is spectacular, except that it's all the same pieces from the older games. I had no trouble with duels, other than that they end too quickly. I often get the the enemies Main Camp and before hitting anyone, I'm in a Duel with the General, and a flick of my finger and the Level is over. The maps are good, definitely the right size for a portable game.
The problem is the game isn't really anything new. If you're a fan of DW, it's great because it's a great DW game, but you're not missing anything if you don't check it out. If you're new to the series, it's a great game to play, but doesn't give you the same representation of the story that you can get in other titles.
It's a great game to pick up and play for trophies and all, especially if nothing else catches your eye but if there's something else out there, don't feel bad about passing on this.
