Excellent hand-picked games, 14-day refund policy, always DRM-free.

We want GOG.com to be the home of games that are both excellent and really worth your time.
In today's gaming world, we're seeing more and more titles that become hits before development dwindles down. We want to give you a way to enjoy what these games have to offer, a way that's comfortable and fair to you — the GOG.com way: that means evaluating each and every game, a 14-day no-questions-asked refund policy, and more.

That's why today, we're introducing the first five games in development:
Starbound (-33%)
Ashes of the Singularity (-25%)
Project Zomboid (-40%)
TerraTech (-30%)
The Curious Expedition (-15%)

The GOG.com way.
First and foremost: we're hand-picking only the games we can truly stand behind. Offering a selection of the most promising titles, and those most highly requested on the Community Wishlist, is our way of avoiding bloat and ensuring that every game will be worth your time.

It takes some confidence to discover games that are still being shaped — and to build that trust, every game in development comes with a simple refund policy: 14 days, no questions asked. It doesn't matter if you're having technical issues, if you don't think the game is sufficiently fleshed out, or if it simply doesn't click with you — all games in development can be returned for any reason within 14 days of purchase.

The GOG Galaxy client should also come in handy for games in development. It lets you control updates manually if you want, while the rollback feature allows you to easily restore any earlier version of your game if an update breaks something or makes unwanted changes. For games in development, rollback will also track and create historical snapshots throughout a game's development. That means you can always revisit any point in a game's history — for fun, or for science.

It's your call.
For those of you who prefer to wait for the final release, nothing will change. Once a game leaves active development, we will be making the announcement and giving the newest release proper exposure. Basically, business as usual.
