I've been playing through Revelations and keep finding myself wishing I had the Dagger of Brutus to play with. It was by far my favorite weapon in Brotherhood, with its' unique kill animations, and I can't for the life of me figure out why there's never been an attempt to include it in ACR. Don't get me wrong, Vlad Tepes' sword is a great weapon and fills the role of "unique kills weapon' but... well, one's great, and two's better, right? I would gladly pay for a DLC that offered me the option to wield the dagger along with Vlad's sword, and was wondering if any of the rest of the ACR players out there would do the same.
Who knows? Given that the engines for ACR and ACB are the same, we might be able to convince Ubisoft to include one last DLC before AC III comes out
