If your advances relate to the use of digital games with an educational purpose then there is a large research community around the subject area of serious games and virtual and augmented reality with many conferences. For example, please look at the conferences promoted by the Serious Games Institute at Coventry University in the UK or where their members have published their work (although this now seems to be defunct - I could only find this link: https://pureportal.coventry.ac.uk/en/organisations/serious-games-institute).
If you mean gamification in another sense then I'm not sure what the closest research community is.
