All the things which were not in the initial release just add replay value for me (although switching on the inside jokes on the second playthrough would have made more sense than switching them off... but I'll try that anyway!).

On a side note - not sure someone already mentioned it in the forum: Judith Holofernes has released a video for her song Analogpunk which references several computer games, including Thimbleweed's signature shot at the bridge.
