This was posted on steam for a new indie game...might be an idea.
It certainly would be an idea and something I'm sure many in the community would be willing to support and report on bugs and stuff to help make PG what it could and should be.
On the flipside, Early Access games (which are basically still in ALPHA/BETA state) usually are offered at a discounted price from what the final release will be. Joining the Early Access means you will get the final release build at no extra cost, so what some folks do, is buy the Early Access because it's cheaper and then not actually play it, then just wait until the game becomes a final release, log in, get their updates, and they have basically saved on the price of the full game, but not joined in with any of the testing, lol.
