If you think about it, it should be, "Whom is on first?"

So Lou was right for responding the way he did.

Rjshae my man, you've been playing Fallout III so much, it managed to kill your sense of humor. :)

Which ones? Only one I can think of is the additional story content that will take players to lvl 20.
Some also seem to be less than what they asked for (like the goblin companion) so I guess it evens out.

For all I know they're not making GTA6 where 90% of funds would go only for music licenses.

Well it depends. The Archetype goal seems like there could be a lot of unique coding to make it work with the potentially new ability additions, so I'm guessing that could take a chunk of time. Depending on whether they include party banter, each new companion can add a significant amount of conversation branches and voice-over work. Finally, the extra story chapter could potentially require a lot of additional labor with new areas, new creatures and NPCs, lore, art, items, conversations, effects, and so forth.

My guesses at any rate.

If you checked out their graph most of the money goes on art. Archetypes need little art.
New companions does not need a lot of art as well and most of the game will not be voiced.
New story chapter will be more effort but they can probably do that last when they are practised and got lots of assets to work with so they will be more effective.

Yes I saw that chart, and presumably it applies to the base funding. The stretch goals are extras that may require a different distribution of assets. You can't automatically conflate the two.

Lacking other info we can assume they are going to keep to their current workflow and expenses should be simialar.

You can assume all you want. Odds are good it won't work out that way. Plans rarely do, especially when they are amendments to the original forecast. Scope creep will kill you that way. ;)

Wrong game rshae, no feature creep here. Luckily this isn't Pirates of Eternity.
