It's everything. I bounced off cos it was said there's lots of random side stuff and usually I hate that but even the fucking squatting mini game is fun. Everything about this game is perfect, combat is addictive, mini games are all solid, it's camp and goofy as all hell, characters are baller, cutscenes are baller.
For someone who never really jived with the original this really lets me appreciate what it had going on by wrapping it in a genuinely fun experience that just doesn't seem to get boring or even stumble in pacing.
My only complaint with the first one is that I don't like the pacing. Segments of the game that were quicker before get drawn out much longer than they should be. I have zero complaints about the minigame content, it's shit sidequests that lead to a chest with some item I don't really want or need but do just for the sake of my obsessive completionism that bothers me. A lot of that is filler.
Part of the issue is that the original game has perfect pacing.
Anyway I have heard that if you do this in the second game (rebirth) you will burn out so I'm sort of worried about whether that will happen. I have so far not touched Rebirth for basically that reason. I'll get round to it eventually.
