Plenty. NBA Jam was a pretty faithful reboot/remake of the original games with today's players and I think it's kind of underrated; the situation with NBA Elite 11 certainly didn't help matters. It's fun and plays a lot like the originals, though that means the CPU can be a bit cheap at times. Classic Campaign is familiar but a little repetitive (and you're locked to one team per campaign), while the Remix Tour changes things up but again, the CPU is a bit cheap when it comes to some of the boss battles and other challenges.
On Fire Edition was a huge improvement. As big a fan as I am of the original games, OFE is probably my favourite arcade basketball game. The Real AI makes playing against the CPU a lot less repetitive while being challenging in a fairer way, most of the time. They combined Classic Campaign and the Remix Tour into Road Trip, where you can select a new team for each game (kind of like the old ladder/tournament mode in the originals) and the challenges are pretty fun and varied. It's also received a couple of roster updates, though none of the newly added players are referred to by name in the commentary.
For what it's worth, online support for NBA Jam has been discontinued, while it's still going for On Fire Edition. Note from FF: This post is from 2013, so I don't know if this is true anymore.
Both are fine games, but OFE is definitely superior with noticeable differences in the way the CPU plays and a better game mode that can be played solo, with someone else on the same console or someone online, all without starting a new game. EA did a fine job with it.
