I just like Parappa in earnest. I find it cool that the definitive earliest rhythm game also has a loose sense of rhythm, like there's something interesting about a rhythm game that can be tackled in a non-rigid path. But putting aside it's relation to other games (since most rhythm games take after the also great and straightforward Beatmania), I just really like Parappa in earnest. And I like it's earnesty, the characters, the music (it's all good!), the cartoon-like setting and atmosphere... it's great.
