Okay. You overpaid and people can get the game for a quarter of that.
Okay let's break this down, shall we... If you've been playing since release because you wanted the game then and you purchased all DLC's/Expansions as then were released or with-in a couple of weeks.
Galactic Civilizations III core game sale after release $29.99
Ship Parts Launch Pack / Designer's Toolbox (unreleased founders only value $9.98 - matches cost of 2 DLC's)
Map Pack DLC $4.99
Mega Events DLC $4.99
Revenge of the Snathi DLC $4.99
Soundtrack (Passed), however, founders get this at value $9.99 - sale $4.99 (Passed because no extra value to core game)
Precursor Worlds DLC $4.99
Mercenaries Expansion Pack $9.99 (sale)
Builders Kit DLC $4.99
Rise of the Terrans DLC $4.99
Altarian Prophecy DLC $4.99
Expandalone (now expansion per interview) sale est $19.99
That is a total value of $104.87 to $109.86 for those that would have purchased everything as released and have been playing everything since the beginning.
Now for those that just go for the gold version, yes you could get everything currently out with good sale for about $45 but, that would not include upcoming (expandalone) and if you paid $19.99 for that you would be already at about $65 and that's not including the extras that the founders already received plus a product that is 18 months to 2 years removed from release.
Good Value for the $100 Elite Founders Edition.
