Colludium Great news! My game was also on Groupees and got the exact same ratio of yes votes and got greenlit a short bit after the bundle ended. So I think you'll get the same result
Just a heads up. There is a downside with the bundle which you'll probably see after the release on Steam. Because after your game is greenlit you'll have to send steam keys to everyone who bought the bundle (if you don't send keys you'll get many bad reviews) and many many of these keys will end up on G2A.com and Kinguin and be sold for a price far less than your steam price.
And more and more people buy their games from these sites and steam sales will go down until your free keys are sold out. So be careful with bundles and giveaways and think once and twice if the publicity generated is worth it.
Once your game launches you will be approached by MANY asking for giveaways to promote your game and you have to be careful so you don't end up giving away too many keys. Because that can hurt sales for months to come. You'll always sell a lot the first week but after that it might change. So don't get too excited the first days
I havent done much else than the Groupees bundle but most of my steam activations everyday is from G2A and Kinguin and I don't get anything from those sales. But I still sell enough real steam keys to keep it up so for me it was worth it to get Greenlit and I think Groupees is a really good Bundle to join during the greenlight process.
But I would never enter a bigger bundle where you might end up giving away 20 000+ copies of a game for a 95% discount. That would be like sending the game into the discount bucket even before the game is released. These bundles are better to enter during the end of a games lifespan.
Speedrunners is a good example of a game that have suffered from bundles. Most people knows about the game but they have entered so many bundles so you can buy the game from various sites for almost nothing now and that will hurt the sales for a long time to come and maybe forever.
So be careful and think once or twice before entering giveaways and bundles in the future. I'm not saying bundles are bad because they can be fantastic if used right.
There are many threads about this on the steam developer forums which I recommend you read the first thing you do after entering steam
Best of luck with the Steam release!
