So, which NFS DS titles have you played and enjoyed the most? I'd like some really good racing action with something interesting that hooks you on - supposedly Carbon and ProStreet are good, but the newest Nitro sequel sucks. What are your thoughts on the NFS DS games? EDIT And I'm wondering, which ones have an open world/town or something which you can roam before getting into a race? So that you don't have just the races, but also some "space between racing", like in some PC NFSes.
