Perfect example of 2K fanboyism was just posted on my Monday Tip-Off article:

The funny thing is, I didn't even criticise NBA 2K18 itself, really. I said I didn't care for the story, and beyond that, the rest of the article was pretty light-hearted. I also talk about how I enjoyed MyCAREER in NBA 2K17! Gotta love how fanboys accuse others of being biased, and trot out the same tired and unimaginative "critique" because someone offered up an opinion that was less than gushing praise. Ah well. I'll just go ahead and mark it as the spam that it is.
Getting back to the topic at hand, the only NBA Live I feel skewed too much towards an arcade style was NBA Live 2003, due to Freestyle Control being overpowered, the exaggerated blocks, and general pace. Even then, it was still five-on-five gameplay with real rules, playcalling, detailed player ratings, etc. As I said in the NBA 2K18 section, to me the arcade style is distinctly different, and refers to the gameplay and aesthetic of titles like NBA Jam, NBA Street, and now NBA Playgrounds. While Live 2003 came the closest, I don't think any NBA Live or NBA 2K game can fairly be described as arcade.
What I would say is that NBA Live has taken too casual an approach to the sim style, whereas NBA 2K has taken a more hardcore approach. The latter has worked out well, without alienating gamers. Of course, beyond fundamental mechanics such as playcalling, detailed ratings, and five-on-five gameplay, NBA Live has also introduced elements like Synergy Sports data that are definitely geared towards a sim approach. However, the more casual approach - at least with default sliders, in some cases - has yielded some unsatisfactory results for gamers who want a more realistic experience.
To that end, I think "arcade" has become a euphemism or shorthand for "falls short of expectations as a sim game", at least for some people. I can understand that, but to me, the term refers to a style that is, as I said, radically different to what we've seen in any NBA Live or NBA 2K game. Of course, we can always debate semantics and nomenclature, but I think we're ultimately getting at the same thing: in some respects, NBA Live isn't as realistic as we'd like a five-on-five game (that is intended to be sim-oriented) to be.
I think NBA Live 18 has a lot of the basics in place, but the biggest issues it needs to address in terms of realism are shooting percentages in the paint, and playing styles. Right now, it seems every team has an offense revolving around attacking the basket. That's not to say that there aren't any midrange or three-point attempts, but there's a bit too much driving, and not just because of defensive errors. I feel like some of this could be fixed with tendency and slider tweaks this year, though. Animations and physics might come down to the engine, but with some tuning updates and patches, NBA Live 18 could make some more pleasing strides. It's not where I'd like it to be yet, but it's got the building blocks in place, more so than it has in a long time.
