Hmm, been doing this awhile, lets see;
Group 1:
Christmas 1980 - about '82. BX days. It's myself, my brother, our cousin, and we added a friend around Easter of '81.
Group 2:
'82-'85. BX+ AD&D1e, other games. Lose cousin & friend, add two other friends & one's little brother.
Group 3:
'85-'89. High School. BX+, lots of 1e, some other stuff & BattleTech. Lose brother & one friend. Add two other friends. + a fair # of others coming/going.
This group would continue, mostly in the summers, '89-'94/95.
Group 4:
'86-'89. High School. Playing alot of non-D&D stuff with a nearly completely 2nd group.
Group 5:
'90 - '95/96. College years. All kinds of gaming with a
very large extended group. Games had significant overlap so I don't think it's really possible to count this as anything but 1 giant group. We just played different things on different days with varying mixes of us....
Group 6:
'96-'2k. MTG & miniature wargaming group(s). Lasted until that particular shop closed (owner simply retired & moved someplace warm
)
Group 7:
2k -'06. New shop, actually closer than the previous one to me. A LOT of miniature gaming. Board games.
Almost no RPGs.
Group 8:
2k-something - 2012. GenCon. I played in a game that continued year to year & had a consistent core of returning players. I guess that's a group....
Group 9:
2006 - 2008. A friend from group 4/5 has returned & is looking to set up a D&D game. 3.5 at the time.
Myself, him, his brother, and two of their friends.
It's his fault that I was drawn back to RPGs from the war torn 28mm tabletops of 40k etc.
Group 10:
2007- 2010. A couple of friends from group #5/college days opens a shop in the area.
A LOT of gaming - RPGs, Minis, board games, MTG.... Also a fair mix of people from group 5+ as well as new people.
Shop closes in 2010 & is a good example of why you often hear advice not to go into business with friends.
Group 11:
2010-2016/2017. Miniature games, alot of HeroClix. Eventually fizzled out/splintered as it got to a point where there were three distinctly different & incompatible playstyles. And then most simply burned out on the Clix due to never ending errata.
Group 12:
2008-Oct. 2020. RPGs, mostly D&D/PF. Was a sub-group of #10. Myself, two people I'd known for years, 2 others. Playing at the shop was simply convenient. When the shop closed we took turns hosting. Some others come/go. #s drift up/down, but there's always a stable core of 3 of us.
The pandemic + politics of 2020 finally ended this group.
One guy simply burned out of all gaming (we pretty much all do that at some point) and quit (for now), meanwhile the friend on the political Left & the friend ever further on the political Right decided they just couldn't play together any more, leaving me, the moderate, in the middle with no Sunday game.
Eventually Mr. Left & I will play something together again once the pandemic eases. Mr. Right..... ?
Group 13:
2010-2016. Mostly AD&D1e. All good things come to an end though, including this campaign/group.
Group 14:
2010 - present. Miniature wargames & board gaming with various sub-groups at the current shop
(there's always a current shop in my area. one opens right as another is closing). Some age old familiar faces/friends, always some new....
Group 15:
2015? 2016? The year 5e came out. Played in a group running HotDQ/RoT.
Group 16:
2016 - present. Various permutations of the current 5e game. Player mix shifts campaign to campaign, but there's consistent people. Some old friends, some new.
Group 17:
2017?18? - early 2020. Took over running the Fri. night game at the shop when the DM changed jobs.
2020 & now a permanent change in shop hours has ended that.
Group 18:
2019 - present. Mini wargaming with a virtually new circle at the areas newest shop.
Shop had just barely launched mid-'19. 8 months later & 2020 tries its best to derail them....
Group 19:
There's a small group of us who've known each other for ages & ages who get together for dinner and Axis/Allies every month - 6 weeks, schedules etc permitting. We've been doing this for years.
2020 has
increased our playing thanks to work-from-home/lay offs/no vacations, kids school events, et/other games being put on hold.
So now it's like every 3 weeks & we vary it with other board games. And occasionally other family members join us.
I predict there'll be a Group #20.
Most likely my left leaning friend & I will put something together post pandemic.
Or I might get into a 5e game as a player at the areas newest shop when that becomes feasible again.
Maybe those two things will be combined....
