Blue is literally-
>Monster Hunter; only Low Rank and 10 large monsters to hunt, must hunt them at least 30 times each. Palicoes repeatedly spout cat puns and memes so no change there Then you unlock the Arena which has the other 60+ monsters, all at HR and Grank. However, they're pretty much impossible solo and you dont get any carves, just like regular arena
But its okay you can just buy whole armor sets using Arena coins
>Mario; only 5 worlds, all world 1-1 themed with retro callbacks, no enemies beyond SMB. Blocks often spell out memes. Bowser says "my face when!" when he's plunged into the lava.
After the last castle, theres 3 challenge castles you can complete. They're longer than the other levels and well designed, pretty fun, with various challenges like "time run" and "coin run" and...thats about it. Only 3, though.
>Call of Duty; complete jizz campaign mode with all the fun guns and maps found in online multiplayer only OH WAIT
In any game, I'd rather spend hours on a decent whole game, rather than slog through hours of fluff to get some simulator of the main gameplay mechanic which I'm expected to play for hours.
