I'd argue we haven't got a lack of games. More like a killer game that 95% of FG will play together is what I think fits what you've said.
Funnily enough we actually struggle to get all people into parties of late. Overwatch is the flavour of the month atm, however imo most seem to crave that PvE, MMO type-esque experience.
I just don't think Destiny is dead yet. Yeah, yeah, I know (Bungie still haven't paid me for their services yet). I just think the raids were great to learn and by the time the next expansion hits they'll be a game to work together on again. The clan objectives is something that would be great to get back into again, lots of us helping to get rewards for everyone.
Maybe we do need to find a solid PC game for the community. I'd argue more need to jump on the Minecraft server (including me) as its a game that brings people together.
Last thing - lets get back on setting up lots of game nights where lots of us can get on. Even things like Cards Against Humanity. Just keeping feeding the fun shit to all. Thats what we do.
