I agree, but i am gonna also have to point out that UFC 2 doesn't even compare or come close to UD3 and that came 4-5 years ago.
EA UFC 1 comes close to EA UFC 2, because the little things it had for it, they worked fine and i had overall more fun than what i am having with EA UFC 2. EA UFC 2's stand-up is plane and simple broken and the poor matchmaking with it's delay is also ruining the grappling advantage on clinch/ground game, making that broken as well.
To be fair, putting EA UFC 2 next to UD3 is like putting Fifa 2016 next to PES 2012 and that's not a good measurement to take at all..
They are on a different league and the point you make about nothing else coming close to EA UFC 2, it's not suprising really, it's the only MMA game on the next gen and on the last 2 years(pretty much 4 years,since EA UFC 1 is it's predacessor and it also didn't have anything to compete) so the visuals and the physics alone should earn that for it, but the fun factor and the longevity of it, just isn't there.
It's not like there are tons of MMA games out there to say my top 2 MMA games are these.
