Playtesting and Origins!

Posted by Chris Pramas: Green Ronin Publishing (Creator)

Hello backers!

The past few months have been focused on the design and playtesting of the decks of Sentinels of Earth-Prime and I'm happy to report that it's going great. The fourth version of the playtest decks are currently having their tires kicked and everything is coming together nicely.

Last week both Green Ronin and Greater Than Games were at the Origins Game Fair in Columbus, Ohio and this gave us a chance to get together to talk about the business side of things and do a playtest together.

This was the first time we've actually had the whole team in one place so we were able to cover a lot of ground and make sure everything was on track for the next stage of development. In addition to the boss Ronins (Nicole, Hal, and myself), we had Steve Kenson (designer of Mutants & Masterminds and creator of Earth-Prime), James Dawsey (art director for this project), and Christopher Badell (Greater Than Games, designer of the Sentinels games). 

The following day Christopher, James, and I met up for a playtest of Sentinels of Earth-Prime.

I played Lady Liberty, James played Dr. Metropolis, and Christopher played Lantern Jack in a battle against Argo the Ultimate Android in the heart of Freedom City! Argo has powers that mimic those of members of the Freedom League, so this was a challenging fight, particularly with none of our characters being big damage dealers. Nonetheless, we prevailed, saving Freedom City once again!

As Christopher designed literally every card of Sentinels of the Multiverse, I knew his new decks would be good. My primary concern was that they capture the right feel for the Earth-Prime characters. Back in April we had Steve go over the decks and give Christopher some notes on story and character. That and the continued playtesting have honed the characters so they provide a fun Sentinels experience and a great Earth-Prime experience as well. 

At this point the major design work for the game is done, so it's a matter of nips and tucks to ensure the decks are just right. We said in the last update you could expect the game early next year and that is still the case. Right now we are in the lead up to GenCon, our biggest convention of the year, so things are in overdrive at GRHQ. Among other new releases, you'll be able to get the Basic Hero's Handbook for Mutants & Masterminds (check out Crystal Frasier's recent Ronin Round Table to find out more about it). I will be back with another update after GenCon.

Happy gaming! Hope you all have a super summer!

      Fantastic update! And looks like you had a bast play-testing at Origins, wish I could have stopped by. Can't wait to do some play-testing of my own. CANNONBALL!

      Thank you for answering my question. I was getting worried I had almost missed it!

      The Backer Kit will be towards the end of the year. We prefer to do it closer to release, as shipping rates can change. As for PAX Unplugged, we may have a mock-up there. Unlikely to have any advanced copies from the printer yet.

      Very nice. Still keeping my fingers crossed that it will eventually make its way over to digital, (about the only way I play these type of game regularly these days), and it becomes the often talked about, but never confirmed or denied, Season 3 of Sentinels of the Multiverse Video Game. Well, at least the option for existing owners to add it and not have to buy the game seprately. :)

      So here's a question for you. Is this game going to have a playable version of some kind at PAX Unplugged near the end of this year? Or are we way too far out to be asking that kind of question?

      Thanks for the update.
      I hope that now, people saying you are doing nothing and didn't care about this KS will finally see it wasn't the case.

      Now ... i have to open photoshop and read the few cards that are readable. :)

    10. Curtis D Bloom on

      When do we get the backer kit to pay for the add-ons?

    11. Steve Kaylor on

      Wonderful update! Thank you for the great info, and I can't wait to (hopefully) see art assets when they start getting put into place!

      Will you have playtest decks at gencon?
