I'm pretty much the same, started playing the DayZ mod back in 2012, good old Arma II
The recent standalone update made me start playing it again but this August and the release of the beta will be a big milestone.
on Arma III I tend to play the DayZ and Exile mods mostly, used to play Life quite a lot. King of the Hill too.
I've only played a dozen or so hours on PUGB myself so that's all good. We should try and get Rib (AKA Plastic Gurning) on too.
I tend (like most folk in the UK) to play on the US servers as they seem to be less laggy than the European one.
