A bit of a shot in the dark on here perhaps, but me and a small group of friends often meet up Sundays at Chimera Nottingham, Beeston -
https://en-gb.facebook.com/chimera.leisure/ ,
https://www.chimeraccg.co.uk/ - to play a wide array of different games from morning till closing! I know of a few war gamers who have expressed interest in playing in the past, so I thought I'd make it an open invitation for anyone looking for a casual group, or a callout to anyone with a pre-existing group who might want to mingle
Imperial Assault (the recent favourite!), Chaos in the Old World, Forbidden Stars, Cosmic Encounter, Sheriff of Nottingham, Betrayal at House on the Hill, Blood Rage, Relic, Dungeon Quest and King of Tokyo are to name a few of the boxed games that get trotted out, not to mention regular casual Magic the Gathering and more recently some Commander. Hope to see some new faces!
