After finishing Sleeping Dogs and loving the experience of laughing along with a game again, I decided to replay Anachronox. Had to repurchase it from Gog as it turns out I've lost my original discs. But the repurchased version has all the unofficial patches too, so it's no bad thing and it was less than £4.
It's 10 years old, so the graphics are very ropey, but the humour and writing more than makes up for it. It's one of the few games to ever genuinely make me chuckle.
Why don't more games go for humour instead of trying to be serious/epic? I love games that make me laugh.
