I said that overall House Party is better. I've seen better implementation of various elements in lots of other games, but I am talking about total package. Most games do like one or two things VERY well, but they don't seem polished and outside of the few things they do well, the rest seems very janky. Not that House Party doesn't have its share of jank, but to me, House Party seems overall the most well-rounded and polished. Just my opinion. I've played plenty of other games, and while I agree certain elements in other games are done very well, even better than House Party hands down in some cases, House Party still has the best overall experience and implementation IMO.
There are some good scenes from NLT, but to me all of their animations seem very stiff and uncanny valley. Even just the basic idling and walking animations seem very unnatural. House Party weirdly seems to avoid that. Probably because NLT are clearly animating the characters by hand, and House Party uses motion capture. Plus maybe the comedic setting allots a bit more forgiveness, I dunno, but I don't get that feeling like I am watching robots. House Party is also not a visual novel or RPGMaker style. I hate that game play format. It does a lot of justice to HP that it always feels like you're playing a modern game no matter what, not reading a story or switching from a high quality cutscene to playing a game that looks like it should be being played on the original Nintendo.
