>>714482708/vg/ is only usable for generals about video games you actually have to play and as much as I enjoy it I have to say that neither rimworld or df really qualify but neither do 90% of the generals on the board
/vtg/ was fun while it lasted but fatshark being fatshark meant that the game getting a meaningful update once every couple years meant it was destined to die and get absorbed into the coop games general which is just a giant graveyard
/domg/ is probably the general that spends the most of its time actually talking about the game because its so involved and the multiplayer play by mail aspect works very well in an imageboard setting
/aceg/ is either talking about the games (mainly scraping the internet for any ace combat news at all) and otherwise general plane autism but the shitflinging is few and far between
/twg/ has lots of discussion and campaign posting because of the minutiae involved similar to /domg/ but it does have a good bit of faggotry going on because of how much reddit has latched onto warhammer in recent years but its not really their fault
if anything the warhammer games saved /twg/ because it was basically on life support beforehand but the unit and mechanic variety makes for good discussion
