What do the hell do I say about No More Heroes?
A subversive, funny as fuck, parody of the sandbox action genre (a popular style of game at the time)
It's story feels like an edgelord take on Scott Pilgrim, and the ending is a mindfuck that forgets what the fourth wall is.
I found it's combat exceedingly fun, and I found the lil minigames jobs in-between each story level to be oddly enjoyable.
