FOR SCIENCE DOWNLOADS
Upgrade Kit to turn your Retail For Science edition into the KS version (mostly).
Includes bonus cards and tokens, but does not include the Monochrome Block set.
Was a bit nervous about missing the Monochrome Block set, but the bonus cards fill in the gaps nicely and make the retail copy feel like the full Kickstarter experience. My group noticed the difference immediately on our next game night.
The tokens are a nice weight and fit perfectly in the card box. Really fills out the retail version nicely, though I wish the monochrome blocks were included.
The bonus cards alone made this worth grabbing since I already owned the retail version and didn't want to rebuy everything. Only gripe is the Monochrome Block set isn't included, but for the price it's a solid upgrade.
