While Dynasty Warriors Origins is looking awesome and already getting some good reviews, I think I'm passing on it for now- the main reason being that I really don't want to be stuck playing as 'generic NPC dude' for the entire game. It's a big head scratcher to me why a series known for a huge number of playable characters and custom characters in its Empires games now has you just playing as a single one who can't be customized.
Although he can use different weapon types, apparently it's limited to only 10 weapons total. This sucks. And it sucks even more because I really liked the demo a lot. It's pretty fun to play and a big step forward for these games, but the campaign is supposed be something like 30 hours long for one full playthrough (and there's a point where you need to align with one of the three kingdoms, which changes the story up, so it's a huge RPG-like campaign that you need to play at least three times to see everything) and I'm just not really sold on the idea of playing as NPC dude for that long.
I hope they patch it to allow for you to play as anyone, add in CAW options, or play as your partner character for as long as you want. That might help. But to me this seems more like a "wait for the XL version or sequel" type of game. Supposedly no XL version or equivalent DLC will be coming, but this is Koei we're talking about so I'm inclined to not believe them on that.
