The Develop 100 will return in June and will name the top British game studios - and now's the time to convince us you should make the ranking.
Studios of all kinds will be featured in the UKIE-sponsored book - new or old, established, in-house or indie.
And for the first time we are allowing UK studios to submit details on their business.
Here's how it works: we've set up a survey form here which asks for basic information about your studio plus, and most importantly, details across four key areas: Heritage & Reputation; Commercial Success; Creativity & Product; and Potential.
These categories will help us understand your activity - whether you are a new mobile outfit with no games released or a console studio with lots of titles under your belt.
The Develop team will then read through and grade each submission in order to formulate our top 100.
Our popular digital book will then be compiled, written and published at the end of June, with commentary by our team of games industry experts.
That's not all: the Develop 100 will also offer a glossary listing all 500 studios in the UK, providing contact details and formats they are working on.
Data for this section will also be collated by Develop and studios will be listed for free - but contact Alex.Boucher@intentmedia.co.uk for more details on premium space you can book in the glossary for your studio.
Ultimately, the first volume of the 2013 edition of the Develop 100 will be one of the most comprehensive overviews of UK games studios yet released.
But we won't get their without your input: click here to start filling in a submission form for your studio.
The deadline for submissions is May 17th.
The Develop 100 has been published by Develop since 2005 - over the years we have chronicled the best studios in the globe based on a variety of metrics - retail revenues, review scores, industry reputation and so on.
Last year we published two volumes. Click here to download 2012's edition, which features a top 100 of global developers based on UK retail revenue, and a ranking of the world's best 100 games based on critic vote. The 2012 edition costs £1.49 and is available on iPad and through the browser here.
Further volumes of the 2013 Develop 100 will be published later in the year.
The Develop 100 is brought to you in association with UKIE, the trade body for the UK games industry.
