I reserved Ryse last week. The more I've read/seen about it, the more it looks like it'll be fun. I haven't decided if I want to buy or rent DR3. I wasn't a big fan of DR2 mostly because of the ridiculous time limit, but that is no longer required in DR3, so it is tempting.
I'm really looking forward to ACIV because of all the naval stuff. That was my favorite part of ACIII.
