i have madden from 1989 sitting around somewhere i think... it'll run on 8-bit systems though i believe...
ESPN 2005 looks good. I don't think i'd bu madden for anything but pc... i like my keyboard and my better graphics
one thing i don't like about madden though is the announcers... i'd love them if they were anything like real announcers, but everything they say is super generic and repetitive... i really think the should spend more time cleaning that whole system up (and learn how to use cross fades on the speech :P ).
