User blog comment:Rutgerman95/Doom 64 console port: TC or EX/@comment-98.198.4.247-20110216044737

Doom64 TC suffers from several inaccuracies, mostly minor gameplay related stuff like player movement, level lighting, some enemy behavior, etc. Though the TC does have new levels and new types of enemies.

Doom64EX is pretty much the real deal and is meant to represent the full fledged game and not as a TC or a mod. Honestly, Doom64EX is the real experience otherwise if you want Doom64 sprinkled with new content, then go for the TC.
