could be you're just getting older
used to do gaming day with my bros all day
life happened, WoW and TF2 died as well, but we just had our own shit going on and time for gayming went away
best you can hope for is something that's fun and everybody's schedule lines up for an hour or two on the weekend
cherish the time you get, ask your bros about their day and how they're doing
there will be a time when you play a game with your bros for the last time and you want everyone to be looking forward to it (the game is carry my obese ass in a coffin to the city waste incinerator)
