I do have to admit that I backed it at a lower level, in part to get the special green pyramids and in part to simply show my support and be a part of the project. I already have well over two hundred pyramids and pretty much every additional accessory for them that had been already produced, including the bandana. :D
In fact, I bought the boxed sets of Ice Towers and Zendo back when they were being produced. Zendo, in particular, has served as a great tool box for the pyramids. (The color contrast in that color set is better for my color-blindness) The Pyramid Arcade is the super-sized version of that.
Honestly, while I have always been a big fan of the pyramid system, the Pyramid Arcade project has reminded me just how much you can do with it. The part of me that loves researching print and play projects loves the system because it lets me explore new games all the time. And I am sure the Pyramid Arcade only encourage more development.
It has even made me end my hiatus on Superduper Games, since there are pyramid games on that site. (I have no issues with the site. I think it's amazing place to play some very unusual abstracts. I just periodically take breaks from it.)
I have had many years of good play from the pyramid system. I think that the Pyramid Arcade is only going to spark more interest in the system and encourage more games to be developed.
