One of my seminary classmates has an x-box - I’ve never paid close attention to his choice of games but like you said, pretty much anything is probably okay except of course sex and drugs. I don’t know of any priests who are gamers - most priests I know (even the younger ones) aren’t of that generation! Plenty of priests listen to commercial music and again, common sense is the only real restriction on their choices (explicit lyrics are probably not advisable…) I don’t know of any priests who play miniature wargames but it wouldn’t surprise me if their are a few lurking out there. Priests get time off just like everyone else and in that time they like to do stuff that other people like to do - such as surfing, going to see movies, fishing, listening to music, etc.
So what’s it like - well ask me in a few years after I’m ordained

Seriously though, for diocesan priests (that’s priests who mostly live and work in parishes) the work can vary quite a bit. The most obvious things are saying mass and administering the sacraments but in between that there can be a lot of administrative work, as well as pastoral work (like visiting schools, rest homes, hospitals or parishioners). Priests tell me that the work can be challenging at times but that it’s also very fulfilling.
As far as salary goes, well let’s just say I didn’t go into this for the money and Sunday’s off! Diocesan priests do get paid, although not much, and the amount they get can vary between dioceses. In some dioceses, the priests are dependent on the weekly collection, while others receive a regular salary from the diocese and hand over part of the weekly collection. Priests can also receive money for baptisms, funerals and weddings, although not all dioceses allow them to keep what they receive.
Finally, I’m not sure what you mean by “how do they live” but I’ll have a stab at answering anyway. Most diocesan priests I know live either or their own, or with one or two other priests. Their day consists of planned activities and whatever happens to come up during the course of the day (such as sick calls) which can sometimes make for a long day. Other than they eat, they eat, sleep, breathe and do their washing just like the rest of us!
Hope this helps.
