A good ds game is megaman star force. It has tons of replay value and a pretty well written story. I haven't heard of zach and wiki or bwii so I can't help you there. MOHH2 looks good to me but I don't know for sure. Mario strikers doesn't look that good. I know this isn't on your list but Fire Emblem Radiant Dawn is very good. Also Bleach Shattered Sword looks good as well(I watch the anime).
