At the end of the day, based on what I have seen, you are getting an asset (pack) that would have taken someone, for example, 150-200 hours to make (character packs), which at $30/hour (which is cheap for high quality stuff) would cost $4,500 - $6,000, and you are getting it for $90. That is a **** good deal, period. I personally believe that items on the marketplace are generally underpriced. Now on the other hand, that is part of the point: the artist/developer makes the asset and sells it for essentially a 90+% discount to hundreds of people. But these items are all turn-key solutions that work out of the box in UE, which is well worth the minor premium that you pay. I am not complaining at all.
