Your choice of ps2 over xbox based on game availability is correct
and yes the fan is loud it will quiet with time
ps2 can play ps1 game which iirc ='s 700+ games made for u.s market 1100+ games made for european ,asian market
you will need a mod chip to play the non u.s. games
also ps2 titles now range around 400 for u.s. versions
one word of advice unless your fully prepared to take on all maintenance and repair your self do not add a mod chip even a solderless one
currently sony repairs all ps2 optical/laser problems for free
because of a flaw in the laser alignment system
which ill cause your ps2 to stop playing or play intermittently after about 2000 hours of use
I just had mine repaired too much smoking of the ganja and ciggarettes gummed up my laser assembly
