Open Gaming Convention 2024

July 19, 20, and 21

Open Gaming Convention (OGC)  is an annual gaming convention whose goal is to have fun, play exciting and imaginative games for all.  This year we bring over 100 role playing, miniature, and board games to Westford, MA.  This year we are centrally located just 40 minutes from both Boston, MA and Manchester, NH.

For those moments between games, you can browse our vendor room or try your hand at our painting corner.

Year of the Dragon

OGC is embracing the Year of the Dragon as our theme this year. Dragons have captured the human imagination for centuries, embodying power, mystery, and magic. They have a rich tapestry of lore, legend, and endless possibilities for adventure.

OGC is happy to announce the return of the return of our vendor room.  Diversity Gaming, out of Hooksett, NH will be there with a selection of their wares including books, board games, miniatures, and of course, dice.  The store stocks all things gaming, as well as tables, private game rooms, collectibles, and even a comfy area to sit and mourn the loss of your character or plot revenge for a sudden, but inevitable betrayal.  Additional purveyors of glorious goods are lined up and we will update you accordingly.

COVID/Mask Policy

Some game masters have indicated that they would like players at their tables to wear masks to protect themselves or their loved ones from infection. We have a check box when submitting a game where the game master can note this requirement. Masks will be available onsite if needed.

In addition, anyone may wear a mask while attending the convention. We feel this is the best balance between personal choice and safety. Additionally, there is no requirement for attendees to have vaccinations, but we recommend being up to date for your safety.

If you have been exposed to COVID or test positive, please follow the guidelines here.

Harassment Policy

Even though OGC (Open Gaming Convention) is a small convention, we want it to be enjoyable by all.  With that said, there has been a large discussion of harassment at gaming conventions and Lisa and I feel that we need to write down our policy for others to see.  We want everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, religious beliefs (or not) or affiliation to be able to attend our convention and have fun.  We won’t tolerate harassment of our convention attendees and game masters in any way.

All of the following constitute grounds for expulsion from the convention without refund:

  • Violating any federal, state, or local laws, facility rules or convention policies
  • Failure to comply with the instructions of OGC Event Staff (Lisa, John, or Kelly)
  • Using anything in a threatening or destructive manner against person or property
  • Endangering the safety of oneself or others
  • Threatening, stealing, cheating or harassing others
  • Failure to conduct oneself in an age appropriate manner

If you experience or witness any of the above, please find Lisa, John or Kelly and let us know immediately.
