Before I'd moved and put most of my 28mm collection in storage, I would host games on 4x8, 6x12 or 6x18 tables. Haven't hosted a game in 5 or 6 years. Until the pandemic, I participated monthly in another gentleman's basement game group using a 6x18. Sadly I haven't gamed since the pandemic started. Only been painting and building.
In terms of table size being larger, my 28mm game ready collections have driven that. They are SYW (30fig battalions), WWII (1:1 company strength with support of armored platoons), zombie apocalypse urban mass skirmish (hundreds of figures and vehicles), Starship Troopers (multiple platoons nd many many bugs), 40K (1000s of points but normally done as platoon or company sized multiside goal driven fights), Warzone (platoon to company level), and for Fantasy I have several 3rd ed WHFB armies but been focused on fantasy figures for my D&D collection of late.
If I end up doing any mini gaming in the near future, it will likely be dungeon crawls on a dining room table.
It is. And it is not. When it is, and when it is not, is the question or the answer, or both or neither.
