in the local phoenix metro area there are 4 pay to play fields. fighter town and fort adobe are the outdoor fields and vangaurd and tempe paintball are the indoor fields. every field has a different type of play.
fort adobe: i have visited this field but have never played there, they only have one field that looked decent enough to play on but between the price of admission and the lack of players the few times i went there, i never saw the field fit to play at.
fighter town: this is the place that you will find most airsofters on a sunday morning, there is open play on saterday as well, but most players are there on sunday. it has buildings, choppers, vehicals, and treches, also has a great reffing staff and owner.
field rules are avalible in any of the fightertown game threads that many people have posted. in my opinion this is your best bet for outdoor pay to play entertainment.
tempe paintball: this is an indoor field. it is a lil small but is a realy fast paced enviroment. good staff and has guns for rent.
350fps semi auto only play.
vangaurd: a lil over twice the size but its mostly populated by players under the age of 18. also has a manditory 10'med. under 10' you are supposed to yell bang bang or surender.
at both tempe and vangaurd i have had great times shooting at people.
there are also games that are put on by teams 'clubs' on a pretty regular basis in the locals games listings on this forum.
hope this helps.
