My brief review of DoT for XBLA:
DoT is fairly well done. It does a decent job of mapping the fairly complex control scheme to the 360 pad. I almost got 30k in pretty short order. In Enhanced mode, you get the awesome environmental background from the full cabinet version, with a bit of added luster that looks nice.
My only complaint is that very few of the voice samples survived the emulation.
You barely hear Sark laugh a few times when he kills you. Meh.
Despite this, it remains a super-playable game that was WAY ahead of its time, a true classic in every sense of the word that has remained somewhat of a coin-op legend. Of course, it's scarcity as a cabinet and near non-existence on consoles makes it a welcome $5 addition to anyone's XBLA library.
(edit-I think it fared much better emulation-wise than the original Tron)
